Old TVs in which there are expensive details. How to find precious metals in radio components. From the scene, the main thing is that not on the "idle"

How is the recycling process?

This is a technological process consisting of several stages:

1. Sort by type.
2. Recess design of plastic enclosures.
3. Disassembling TVs to the details.
4. Liberation of kinescopes from glass.
5. Withdrawing metals and sorting them by types.
6. Preparation of plastics and metal for processing.
7. Sending to recycling.

But do not think that in our country everything is fine with the disposal of electronic technology, including old TVs. It is easier to organize their collection and preparation for recycling than to run processing production, as well as find the use of recycled raw materials. Collecting and Sorting Waste - Profitable Business, Therefore, there are many companies wishing to do this. But everything rests on the processes of processing and the further use of the resulting raw materials.

Process processing

In Russia, only plastic, some glass and metals are processed from televisions. The secondary raw materials obtained from them are used in the production of paving and ceramic tiles, packaging bags, cement and a bit in the glass industry. All other components of old TVs are mainly destroyed.

Enterprises that produce kinescopes, televisions of the new generation, as well as glass plates find constant reasons for refusing to apply secondary raw materials. To do this, they need to make changes to the production technology, which is associated with considerable costs. And although it would seem that they should be interested in reducing the cost of produced by their products, and therefore, and in lower prices, they do not hurry to change the production technology. Start processing the greater specific gravity of components of old TVs without the development of the base of the use of the resulting raw materials is economically impractical.

There is someone

The only country where state programs for the disposal and processing of all industrial and domestic waste were developed - Japan. But it should be noted that over the past 5-10 years in Russia began to relate to the problem of environmental safety at the government level, which makes hope to decide with the time of the problem of waste processing and the extensive use of secondary raw materials. But this does not mean that now it is necessary to throw out Outdated technique, televisions and other electronics into garbage. We ourselves are responsible for the state of the environment and our health, therefore, should understand the disposal of most waste and outdated equipment.

Electronic PDF version;

Kinescopes served as the source - the source of a large number of useful materials, the use of which will save natural resources and will help reduce the effect of hazardous industries on the environment.

In 2008, the age of electron-beam tubes (CRT) ended. According to analysts, the sales of electrical monitors amounted to only 0.1% (600 thousand pieces) from the total market share, although in 2004 she held 68% (3.18 million pieces). In 2008, the largest world companies announced the termination of the production of monitors and televisions with an electron beam tube. Since 2008, remnants from warehouses are sold. Therefore, the trend towards the development of the ELT market is best viewed by Example 2004-2005. As statistics shows, most of the kinescopes are thrown into a landfill, and not processed. ( kinescope is an electron-beam device that converts electrical signals into light. Its main parts: an electron gun forming a beam of electrons, a screen covered with a luminophore, luminous when a beam, deflecting the system controlling the beam).Environmentalists warn that all the kinescopes should be reworked in the coming decades, otherwise it will affect the environment. But it is quite difficult to utilize them according to the rules, and the scope of application of recycling products until recently has been steadily reduced, so the processors prefer to store CRT.

Fig. 1. Dynamics of the Russian monitors market

From general formulations to specific rules

In the West, not only government agencies, but also the associations of processors, who try to describe as much as possible and describe in detail the requirements for the recycling process, work on the development of the Rules of Recycling of Kinescopes. In Russia, while companies are based on general regulations, such as: the federal law "On the waste of production and consumption" dated June 24, 1998 No. 89-FZ and the Regulation on the licensing of activities for the disposal and placement of waste I-IV classes of danger, approved by the Government Decree of March 28, 2012 No. 255.

In the United States before 2009, enterprises involved in the disposal of televisions and monitors preferred to be buried recycling. Some negligent companies even sold an electronic scrap in Africa and China. The statistics of the Electronic Industries Alliance (EIA) are indicative of the ELECTRONIC INDUSTRIES ALLIANCE (EIA) - organizations developing electrical and functional standards with the RS identifier (Recommended Standards): in 2000, only in America sold 530.9 thousand tons of alloyed glass designed for production CRT, and utilized 8.24% of them.

January 29, 2009 Agency for Environmental Protection (US Environmental Protection Agency (EPA) simplifies the rules for collecting and recycling kinescopes, thereby increasing the share of their processing. Unattached ELT was allowed to store as conventional waste, but in appropriate conditions (for example, at temperatures, Excending the possibility of evaporation of lead). Only processing firms were obliged to dispose of the kinescopes belonging to them after a year of storage. Damaged ELT was stored only during the year and only in special containers.

Problems of processing and implementation

Almost 42% of the mass of any monitor and the TV is a kinescope, and it is its processing that is the main problem of firms involved in the disposal of these devices. On average, 87% of the mass of the kinescope makes up a glass of three varieties. The screen contains strontium, barium, lead, protecting the viewer from the X-ray radiation occurring during the operation of the tube. Manufacturers are used different technologies Protection, the most common of them - the technology of adding to glass up to 12% strontium. Cone of the ELT and the electron cannon area is protected by adding lead oxide. It is impossible to ignore the potential possibility of leaching during the burial of the ELT toxic lead, although the likelihood of this is quite small.

Consider two directions of recycling of kinescopes: first, this is the use of electrical glass as such and, secondly, the separation of it into the components (purified glass and lead) and their processing. First option It was at one time the most popular and mass. ELT glass was used mainly in the production of kinescopes. Also, the screen glasses were used as a mixture in the production of metal or ceramics.

But as it turned out, natural resources preferred at the glass factories. There were two reasons for this. First, each manufacturer of alloyed glass added its patented impurities, the composition of which was not always advertised. And any extra substance could pollute the glass ware stove so that production would have to stop for several hours, or even days. And there was not a single efficient way Determining in advance the exact composition of raw materials. Secondly, the sale of glass has declined greatly when the production of kinescopes comes out in 2008. As a result, the competitiveness of alloyed glass left much to be desired.

Second option (Glass recycling) allowed to save natural resources, but the glass plants again it was more profitable to buy primary raw materials. In addition, not all recyclars operated on with technologies that guarantee a certain chemical composition of products and no emissions. On the currently They have already been invented, so gradually this problem should go into the past.

In general, companies are still easier to get buried on landfills that served electron-ray tubes than to recycle and dispose of them. According to the participants of the meeting conducted by the Environmental Protection Agency in January 2013, 660 million pounds of glass are illegally stored in the United States, which could be recycled.

Now in the West has already come to the fact that state support needs and increase the competitiveness of the ELT glass. This is the only way to make the utilization of kinescopes cost-effective.

Processing Associations began to build a dialogue with power. Their representatives are confident that it is the state that the state is obliged to control the quality of the processing of served kinecopes. In addition, it should introduce the principle of expanded responsibility of the manufacturer, that is, shifting financial responsibility for the disposal of the ELT on the shoulders of manufacturers. It is also desirable that the authorities contribute to the search for new recycling technologies, because the increase in their competitiveness is for the most part depends on the level of their development. The sorting methods used in order to exclude glass mixing with different percent lead, and methods for determining impurities are important. If companies are able to guarantee the composition of recycled raw materials, this will allow equal to compete with suppliers of natural raw materials.

Effect of ETT monitors on people's health and ecology

The next problem with which environmentalists and processors collided with, this is an increasing panic that kinescopes are radiation sources and toxic lead. Indeed, they contain hazardous substances, but without relevant research it is difficult to say how harmful is the burial. In order to correctly assess the seriousness of the problem, you need to trace the entire life cycle of kinescopes: production of raw materials - production - use - disposal (Fig. 2).

Fig. 2. Distribution of power of influence on the environment during the life cycle of the ETT monitor

According to the United States Environmental Protection Agency, the production of ELT affects the environment much more than their burial. For example, in Russia, lead emissions into the atmosphere of glass plants are estimated at 100-200 tons / year.

The most frighten the public two substances used in the production of kinescopes. It is strontium and lead. The first is suspected of radioactive radiation. This alkaline earth metal in its properties is very similar to calcium. Stronging oxide as part of a solid solution of oxides of other alkaline earth metals - calcium and barium - is used as an active layer of indirect heat cathode in the electron cannon.

But the natural strontium and its radioactive isotopes should not be confused. The first neradoactive and small-toxic, it is an integral part of microorganisms, plants and animals. As an analogue of calcium, strontium is best postponed in the bones, but it affects human health, it is extremely rare and only in the presence of concomitant negative factors: calcium lacks, vitamin D, selenium, etc. Strontsia is used as a substitute for calcium in production in metallurgical and The ceramic industry, in pyrotechnics (staining the flame in the carmine-red color) and in medicine (for the treatment of osteoporosis).

The second metal, lead belongs to the class of highly hazardous substances due to its poisoning properties and the ability to accumulate in the body of living beings. Various lead compounds have different toxicity. It should be noted that the likelihood of leaching lead from electrical glasses is quite small.

According to the US Environmental Protection Agency, the ELT monitors contain more than 40 thousand times more lead than in LCD monitors (989 g against 0.025), however, its negative impact on the ecology and health of people is much less than that Conventional glass or copper. It is dangerous for mostly only for workers in glass and processing plants that can poison dust or lead pairs.

Until serious studies have been conducted and quite statistical data collected, it is difficult to talk about the degree of threat to nature. But it is necessary to process the kinescopes not only because of possible pollution of soil, water or air, but also because the kinescopes are a source of a large number of useful materials, the use of which will save natural resources and help reduce the influence of hazardous industries on the environment.

The problems inserted in front of companies are solved in different ways. It is the state control of processing of kinescopes, and continuous monitoring of information about their processing, and the legislative prohibition of the ejection into the landfill of the ELT monitors. In addition, there is a tendency to apply the financial responsibility of the manufacturer for the disposal of the equipment serving its service life. Increase this period of use will help resale or donating monitors in need (in schools, medical institutions and other organizations).

Processors are actively looking for new sales points of their products, and also expand the product line. On the this moment The sector of applying glass purified from lead is huge: from the smallest components for the electronics industry to huge elements of refractory glazing, from household plates to the pharmaceutical industry and solar energy. Modern technologies allow you to control the presence or absence of impurities with high accuracy.

In Russia, this area of \u200b\u200bservices began to develop, and if accumulating all the accumulated experience, then many problems can be avoided and immediately to the European level. After all, if we dispose of an electronic scrap, you need to do it well, otherwise resources will be invested.

| Removing gold and silver from radio components
| At home. PART 1

This time practical experience And the photos are divided by Canadian Joseph Murchison (Josehf Murchison) - link to a detailed article and all photos. The translation of the article made and posted a user Alizar on Habré.

Each electronic board contains several milligrams of platinum, gold, silver and copper, which can be removed from electronic garbage if desired.

It is most profitable to get gold. Joseph Murchinson says that the ancient electronics, the greater there may be gold.

First you need to collect all gold-containing details together. For several months, everyone can give a lot of such details. The photos show what Joseph managed to collect in three months.

Details should be sorted and removed with a magnet to remove gilded steel, which requires a separate process.

Dirt-purified gold-containing fees are descended for one week into a solution of hydrochloric acid (two parts) and hydrogen peroxide (one part). Every day the pot with acid needs to be slightly stirred.

A week later, the solution darkens and the floating flakes of the precipitated gold become visible. They need to be skipped through a coffee filter and rinse with methyl alcohol.

Next, you need to rush the scales into one ingot. The gas melting point is 1063 ° C, so that the usual burner will not cope with the task. But if we treat the gold with a sodium tetrabrator (boorax), then the melting point decreases.

After receiving the ingot, you need to weigh it to assess profits. This ingot weighs a little more than Troy ounce (31.1 g) and costs from 600 to 1600 dollars.

In Ukraine for 1 gram of gold, 330-410 UAH are given as of December 2013 - January 2014. In Russia, the average of 1300-1400 rubles.

| Mistress note: from broken mirrors and Christmas tree toys
| You can get silver

585 Gold sample, or 14 carat, is the most popular. The sample indicates the amount of pure gold in the alloy. That is, 585 is the number of gold parts per 1000 parts of the alloy. The remainder of 415 parts is supplements, such as copper, nickel, silver, platinum ... all makes alloy all the alloy, affects the shade of the ingot.

Gold 999 samples soft.

Check 585 Gold sample can be home with iodine: link to YouTube video. Also, you can use chlorine gold or find on sale a reagent for checking gold.

Noble metals in electrical engineering

Today we want to tell you about the use of various precious metals in electrical engineering. Surely, many of you did not even think about the fact that in the huge number of electronic and electrical devices and devices around us there are elements from noble metals.

Gold and silver have excellent conductivity, so they are used to cover electrical contacts. Silver and gold perfectly oppose oxidation. Many chips have gold-plated contacts, and electrical relays often have contacts from silver.

Silver is used to cover the surface of the waveguides, because silver has a better conductivity among all metals. But on military devices, the surface of the waveguides often covered with gilding - this is done to increase the service life.

Silver on contacts is often replaced by palladium, which does not black and is resistant to sulfur connections. Another very expensive metal - platinum. The ability to work in a wide range of temperatures makes platinum ideal for use in thermal resistors.

Another unusual application of silver

Silver is a very popular metal in electrical engineering, but it has another unusual and non-trivial application. The maximum thin layer of silver is applied to the surface of the photosensitive sensors with inverse illumination.

How harmful old radio components

As a rule, such sensors are installed on expensive cameras.

Silver can split oxygen molecules into two separate atoms. A negative charge is created on the surface of silver, which contributes to the stabilization of time parameters. Approximately the same principle contributes to the antiseptic properties of silverware.

Atomic oxygen in silver vessels is the strongest oxidizing agent.

How much gold in the computer ??? This information can be useful for beginners and simply spectators. You do not have to do this, but you can see my video for any curiosity.

Precious details

Briefly about the process itself, for Extreme This time I dissolved all the parts in the electrolyte with the addition of ammonium nitrate and the food salt. Everything went fine, time took a lot, but it turned out. Then I decided to try to restore the gold with metal copper, and nothing happened, the solution was very dense, and the concentration of yellow metal is very small. Then I applied proven sodium pyrosulfit, everything immediately darkened and the gold was separated in the form of a dark brown sediment, which was delayed on the filter. It didn't work on to rush this time, the sediment scattered, but it doesn't matter to me, I shot a video for subscribers and just random spectators, I think the process itself is understandable and interesting.

Technology extraction of gold and silver from electrical and radio components. Free method for extracting precious metals at home

Once in his youth I had to live near the radiosprot, on the landfill of which radioetal could be collected by the Sovkom, what we did. Many dragged them on the "flea market" and sold radio amateurs, and I under the influence of my neighbor, who all something "chemored" was carried away by the prey of precious metals from some details. Chemism accounted for in the kitchen, as there was no other suitable place, and I, frankly, got great from my loved ones, as the technology of extraction silver and golden is not a safe thing, especially if this business is done in the kitchen environment. I could not get rich, because I was not going to get rich, because at the insistence of my relatives who quickly bored my experiences, the latter had to stop. Soon the family changed the place of residence, moving in Krasnoyarsk regionWhere neither "raw materials" nor a neighbor-chemist was no longer. New hobbies appeared in a new place, but the science of the neighbor remained in his head for life.

Free technology for extracting gold and silver from radio and electric power agents

So, the conversation will begin with the release of silver, such as less valuable metal.

Getting silver from alloys

The source material for the release of metallic silver is silver-containing alloys from which a number of electrical connections and contacts are manufactured.

Preliminary preparation of "raw materials" is that parts and devices intended for processing are removed all too much. First of all, all non-metallic parts (plastics, polymers, semiconductor crystals), as well as metal elements that clearly do not contain silver, for example, parts of contacts that are not in contact with the closure of these contacts.

Having done all the above, you significantly simplify the procedure for dissolving the samples, and the acid will need less for this. Silver-containing samples are dissolved in 30% (by volume) nitric acid at a temperature of 50 ... 60 ° C. Dissolve the "raw materials" with minor portions of mass of 1 ... 3 g, and the next portion is added only after the complete dissolution of the previous one. Approximately the dissolution of 1 g of alloy is consumed 3.6 ml of 95% nitric acid. As a result of the complete dissolution of the silver-containing alloy, a clear solution is formed.

Remember that all this work should be carried out in a well-ventilated room, even if it is a kitchen - the fortochka must be open.

Now on the queue - the preparation of silver chloride and the precipitation of it from the solution. To do this, the solution obtained at the previous operation heated to about 70 ° C is added 7 ... 10% hydrochloric acid, constantly stirring the solution. As a result, precipitate (silver chloride) begins from the solution. Consider, mix the solution and carefully add hydrochloric acid to it continue to complete the cessation of the formation of the precipitate (but it should not be overflowing!). The temperature of the solution is maintained until the precipitate falls on the bottom. Then the solution is allowed to cool to 20 ... 25 ° C, after which it is gently agitated to a transparent liquid above the sediment, a slightly hydrochloric acid of the same concentration is to ensure that the precipitate from the solution fell completely. Next, the solution is left overnight in a dark place, then the precipitate (silver chloride) is filtered off and is dried by approximately 1000 ° C with sodium bicarbonate (drinking soda), taking 1.5 g of soda per 1 g of silver. After cooling the melt, metallic silver is easy to wash away from other melt components with water from under the tap. On this, the procedure for obtaining silver and ends.

And for better perception of the material I suggest to get acquainted with brief characteristic used in this process Chemicals.

Silver (AG). Soft white metal whose density is 10.5 g / cm³. The melting point is 960.8 ° C, does not dissolve in alkalis, but is amenable to the action of acids (boiling concentrated sulfur, as well as nitric at room temperature).

Salonic acid (HCl). Colorless transparent liquid with sharp odor of hydrogen chloride. Maximum acid concentration of about 36%; Such a solution has a density of 1.18 g / cm³. Salonic acid interacts with nitric acid silver with the formation of silver chloride falling into a precipitate.

Sodium bicarbonate, sodium bicarbonate, drinking soda (NaHCO3). White crystalline powder with a density of 2.16 ... 2.22 g / cm³. At 100 ... 150 ° C completely decomposes, turning into Na2Co3. It is used in medicine, for example, for washing the skin if acids appear on it.

All these reagents can be purchased in hozmag.

Obtaining gold from alloys

The initial raw material for obtaining metal gold are gold-containing alloys, from which a number of electrical connections and contacts, chip cases, transistors, clocks, etc. I had to use chips of the following series: 108, 109, 115, 119, 123, 128, 130, 133, 136, 149, 156, 162, 175, 178, 185, 188, 198, 229, 231, 249, 505, etc., as well as cases of transistors type: CT 301, CT 603, CT 605, CT 608, CT 644 and Dr. The characteristic difference of such materials is their golden painting. The content of gold in the starting materials (samples) is up to 10% (by weight). But it should be borne in mind that the content of gold, indicated in the passport data of such products, is often not true, and it usually happens much less than the value given in the passport. And note that the content of gold in radio components made before 1989 corresponds to passport data, but in the subsequent years of gold in radio metal began to add significantly less (by almost 40%) than they promised in the passport. This is me so that they do not build ambitious plans, since it is not always a sheepskin standing, as they say in the famous saying.

With gilded clips of hours, you can work without any trick.

ABOUT pre-training I will not speak gold-containing blanks, since everything should be done in the same way as in the preparation of silver raw materials.

Dissolve the billets with minor portions (mass 1 ... 3 g), adding the next portion only after complete dissolution of the previous one. Approximately 2.3 ml of 36% hydrochloric acid and 0.65 ml of 95% nitric acid are consumed on 1 g of gold-containing elements. The resulting solution, painted in a dark green color due to the large number of copper salts present in it, is slowly evaporated, reducing its volume several times. The remaining solution, several ml of hydrochloric acid (until complete dissolution of the brown residue of iron compounds), and are also poured into a solution of sodium chloride (table salt) at the rate of 0.2 g of salts per 10 ml of gold-containing solution, after which the solution is evaporated with low heating. to "wet salts." Then plot several ml of boiling water and the solution is evaporated again to "wet salts", after which several ml of hydrochloric acid is added again and evaporated again. Such evaporation procedure is necessary to remove nitric acid residues, which will avoid losses of gold secreted.

To precipitate gold to the previously obtained solution of a dark green color, a 0.5% hydroquinone solution (0.5 g of hydroquinone in 100 ml of water) is added at the rate of 1 ml of hydroquinone per 100 ml of solution, avoiding a large excess of hydroquinone.

dragmetals in Kinescope

The resulting mixture is withstanding about 4 hours, mixing it periodically.

The separated sediment (gold) is filtered through a dense filter, washed with water, acidified with hydrochloric acid, dried and interpreted at a temperature of 1100 ° C under a layer of borax, which protects gold from evaporation when heating and melting.

After cooling the alloy, the king of metallic gold is easily separated from the residues of the frozen drill. Everything!

Now briefly used in the selection of gold chimreactles.

Gold (AU). Soft metal density 19.32 g / cm³. The melting point of 1046 ° C is not dissolved in acids and alkalis, but is amenable to the action of mixes of acids: salt and nitric ("royal vodka"), sulfur and nitric, sulfur and manganese.

Nitric acid (HNO3). Colorless liquid with a sharp odor, poisonous, inhalation of nitric acid vapor leads to poisoning, the skin entering burns. Anhydrous acid density 1.52 g / cm³.

Release a strong acid (density of 1.372 ... 1.405 g / cm³) and weak (density of 1.337 ... 1.367 g / cm³).

Hyroquinone [C6H4 (OH) 2]. Colorless crystals, density of 1.358 g / cm³, well soluble in alcohol. At 15 ° C, 5.7 g of hydroquinone dissolves in 100 ml of water. It is widely used in the photo as a developer component.

Bura, sodium tetrabrate (Na2B4O7X10N2O). Colorless crystals, density of 1.69 ... 1.72 g / cm³ dissolves in water (1.6 g of anhydrous salt in 100 ml of water at a temperature of 10 ° C). Used when soldering for cleaning metal surfaces, for the preparation of special varieties of glass, enamel, glaze, etc.

Sodium chloride, sodium chloride, salt salt (NaCl). Colorless crystals, density 2.161 g / cm³. Well dissolved in water. Widely applied in everyday life.

The described reagents can be purchased in business stores, photo-storey stores, chemical stores.

In conclusion, I want to call for everyone who will use these techniques to be extremely neat and cautious. Not to leave unattended chemicals, to store them in a tightwork dishes in inaccessible for the uninitiated and, first of all for children, places, and at the same time never forget that God is escaped.

These techniques are complete, detailed, accurate and, which is very important, proven in practice.

All materials of the section "Miscellaneous - ideas, tips, techniques"

This article matures mainly on Soviet household appliances. Raw materials of this type often falls at the items of receiving scrap metal, where it is bought for the sake of the contained non-ferrous metals. Compared to industrial equipment and military equipment, household appliances contain small amounts of precious metals, but there is no meaning to extract them anyway. Below we will try to describe radio components and equipment components where precious metals are contained and write recommendations for extracting them.

TVs

Soviet TVs are lamp and transistor. The lamps practically do not contain precious metals, of which it makes sense to extract only the output radiation tetrod (the largest lamp on the right under the casing 6p36c, 6p44c, 6p45c, gu50).

Transistor TVs contain such valuable elements: -Microshem in plastic housings -Transistors type Kt814, CT940-Total Type CT310 type, KT502, KT503 -Lodiodes of AL307 in the selector block channels-hectable transistors of the KT203 type in the CMRK block and, sometimes, on other boards. -Conacators km "Units", K10-17 yellow, sometimes red km. -In some cases may contain green km, transistors of other types and so on. Despite this list, you need to inspect all the boards, because There are many different models and performances, and in devices even one batch can stand different parts as containing precious metals and not containing.

Calculators

Soviet calculators contain a significant amount of precious metals. They are contained in the keyboard (gilded board or armor), in the processor (yellow ceramic or plastic chip), as well as in some other details, such as: Capacitors km, chips 140ud and power switch. Some calculators contain a whole set of boards with switches, lamellas, multiple chip and Capacitors km.

Tape recorders

Soviet tape recorders may also contain a number of precious metals. -Choor plastic chips (174UN7 and TD) - Power transistors Type KT802 and similar-sensors type KT814, KT503-agel-type CT203 type transistors, CT3102-agel microcircuits of the indicator controller (in the tape recorders of the lighthouse and the like) - Also may contain Capacitors km, RES -9, silver contacts of switches and other ...

Radiols

VCR

The electronics of VM-12 may contain significantly the number of capacitors km, K10-17 and yellow transistors (type Kt203).

Refrigerators

Both Soviet and modern refrigerators contain silver contacts thermostators, as well as a soldering of the PSR.

Washing machines

Both Soviet and modern washing machines Contain silver contact relays and timer.

Computers

Computers of Soviet production contain a significant number of CONDERATORS km, K10-17, as well as yellow ceramic and plastic chips. May contain gold-plated times, contact pads and so on.

What is valuable in old TVs?

Computers of imported production of various years of release contain a significant amount of precious metals in the processor, processor socket (socket), as well as in contact sites (lamellas of boards). The processor in ceramic lilac cases is especially valued. The processors of plastic, textolite corps contain a slight amount of gold. CD, DVD drives contain gilded laser diode. Imported computers of the old year of production, mainly until 1990 may contain imported analogues of K10-17, which are accepted by the same prices as domestic.

Phones

Old disk phones contain silver dialer contacts. Soviet portable phones (Lyon, Altai type) contain a significant amount of gilded transistors, chips, sites, as well as KM capacitors. The cost can reach several thousand hryvnia for the device. Soviet answering machines and number identifiers contain a lot of Capacitors km or K10-17, and may also contain gilded specialized microcircuits. Soviet automata telephones contain RP-4 relays, silver contacts.

Cash registers

Printers

Conditioners

Soviet air conditioners such as BC contain silver contacts and soldering by PSR. Contemporary air conditioners contain silver contacts of power relays. Small household appliances (irons, hair dryers, kettles, wall clocks and the like) may contain silver contacts, gilded diodes and transistors.

For sure, it is not necessary to look for precious metals in the following devices:

- Luba imported TVs

- Radios.

- Import radio systems, keyboards, mice and other computer perferes

- Radio receivers of imported production, calculators and other China

- Laptops

- car radio

- Audio speakers

- Patifones

- Heaters

— Gas plates and columns

- Hoods and fans

- Vacuum cleaners

- Power tools.

Rhythm of life becomes faster every year. Technical progress does not stand still. It develops rapidly. New models of TVs attract buyers with new technical capabilities.

In addition, large shopping centers arrange sales and offer to buy advanced television models at a low price. When buying a new one, I want to get rid of the old one. It will be better if it succeeds to help out some amount. Where to pass the old TV for money? Below will be options.

For parts

So where to pass the old TV for money? For parts. There is such a way to get rid of the old TV, how to pass it on the spare parts. In no case can not be disposed of devices for a landfill. As this technique It has a certain value.

The fact is that the old TVs have spare parts that can be sold for money. There are special items that will accept the old TV on the spare parts. It is worth knowing that the fee for them is symbolic. Therefore, you should not count on a great reward. These items have such a service as self-delivery. They come and take the used TV. The calculation with his owner occurs in place. It is very convenient. Since you do not need to go anywhere. It is also worth remembering that old TVs may have quite impressive sizes. Therefore, it will be better if they are taken away.

Buying

Sometimes the purchase of old TVs on scrap metal is held. The fact is that this type of model contains a certain amount of non-ferrous metals. This amount is small. Therefore, the owner of the TV will pay a rather modest amount. Points of buying old TVs are quite large distribution. They can be found everywhere. Can be done comparative analysis prices to sell a TV for more expensive. The cost of accepting non-ferrous metals may vary. But it is not recommended to choose a metal collection point that is at a high distance from home.

Since you have to spend money on transportation costs. It will be better to attribute the TV to the closest reception. It is worth saying that it is possible an independent version of the extraction of copper from the TV. To do this, it will need to disassemble and remove the items that contain this metal. On average, the amount of copper in the old TV is about 3 kilograms.

Where to pass the old TV for money? You can apply for sale. This sale option is recommended to use those who have a TV in working condition. There are cases when the old model of technology has excellent image quality. Such a TV is a pity to disassemble or donate on scrap metal. Students will be happy to buy this technique. Also, this purchase option can be suitable for cottages or on the service room of the guard. Options may be several.

Place an ad can be available on special sites that are present in large quantities on the Internet. Some resources are well-known. In addition, the ad can be published in social networks. This method has a big advantage. Because you can contact familiar people who want to be sure that the TV is really in good working condition. Since this type of technology can acquire pensioners for giving, then the fact that many of them are not active users of the Internet should be considered. Therefore, it will be appropriate to place an ad in newspapers. Since this category of citizens reads such editions. This method Sales is the most profitable. Since the seller can designate the price you need. If the TV will not be sold for a long time, it should be reduced. Also cost to remember that the ad should be updated. The more often the seller will do it, the greater the probability of selling this type of equipment will be.

Sale of an old TV collector

Where to pass the old TV for money? Sell \u200b\u200bits collectors. Here we are talking about those models that were issued in limited quantities. You should know that the collector will not be interested in the technique that stood in every apartment several years ago.

But the rare TVs of the old sample can be found to antiques. If the thing is unique and represents the value for a collector, then it will be ready to spend a fairly large amount on it. It should be known that private collections of old things belong to fairly expensive hobbies. Therefore, only wealthy people can afford them. If there is a rare thing, then an important point is that not to be made with it. Therefore, it is necessary to offer such a TV to several collectors and decide on the price. It is worth remembering that for a unique thing you can assign a very high cost.

Reception of old TVs to repair

There is another way to get rid of the old TV for money. It is to contact the repair organization. In fact, such workshops should only use new parts in the repair of televisions and other techniques. But in practice there are cases when they replace the elements from the old televisions released from the working state, which they buy from the population. Here we are talking about models that have been released a small number of years ago. Such instances will be used to repair other TVs.

Since this type of activity is not quite honest, then this fact should be taken into account. It is possible that some repair shops will refuse such a purchase by phone. But you should not give up this idea after the first conversation. You need to call several points and talk with several people. Better if there are familiar who work in such services. Such a principle of work of workshops is based on their desire to save on the components.

Reception of old TVs to repairs to recycling

In cities there are special centers that are engaged in the disposal of old technology, which failed. As a rule, there are several such points in large cities.

It is believed that the ejection of the technique is harmful to the environment. Therefore, it is recommended to recycle it. Advertising about the work of such centers can be found everywhere. Should know what this procedure It will be necessary to pay, that is, to benefit from such an order with an old TV will not work.

Shares stores

Where are the old TV? To the store. They often offer their customers. Large trading networks arrange such stocks as the exchange of an old TV to a new one. The essence of these proposals may vary. Some shops offer in return for several old one new option. There may also be such an action as providing a discount on a new technique. Such store offers are very much like buyers.

Since they have the opportunity to make two actions immediately. Namely - to get rid of the old technology and buy a new one in return. It is worth knowing that the old is accepted both in working condition and failed. There is also such a service as delivery of goods. Store employees will bring a new product and take old. The calculation can be carried out by courier in cash or online on the website of the online store. The benefit of large stores is that they will hand over the old technique in the recycling points that plastic melted and use it for new production. This species Sales benefits buyers, sellers and companies that are engaged in disposal.

I would like to say a few words about what you should not keep things in your home that a person does not enjoy more than a year. It is better to get rid of them. Since they do not bring any benefit to man, but only litto the space. Where to go old TV, it was discussed above. People who cannot part with old things should be overcome their attachment and choose the method through which they will give this thing. Someone will want to sell the old TV. Someone will like the proposal of a major shopping centerwhich offers in return for three old TVs one new. In any case, you should not store unnecessary things in your home.

Conclusion

Now you know where you can do an old TV. Choose the option that you like. Good luck!

Often on the entrances of houses, transport stops and just on the fence you can see ads that the purchase of different equipment is passed. We are talking Basically about broken things or those that are outdated morally. The population thus has the opportunity to get rid of unnecessary garbage. For a businessman, the recurrent of old who came into disrepair of televisions is a good opportunity to earn.

With bought for small money, TVs can be done in different ways. Most often they are disassembled on parts. The obtained parts are made for different production, where there is their reception. New technologies today make it possible to use spare parts secondary. This makes it possible to receive a stable income to the entrepreneur. Often buying household appliances has a home business format. Investments in it are minimal, and knowledge is practically no need. For the development of their case you will need mobile connection, Internet and own living or non-residential area. To this you need to add an entrance, fantasy and a huge desire to get satisfaction from your business.

How to make money on the old technique?

Most inaders do not even guess that they have unique and rare things in the apartment. These are old televisions, radio receivers, radio. Any old technique today in price. If there are no such objects in your house, then they will probably have any relatives. Grandparents and grandmothers are often happy to get rid of those things that occupy a place in the house, and the benefits have not been brought for a long time. How many of them are still in our friends and relatives!

Now the question arises, we are taking the old Soviet TVs organized, and what is their value? The fact is that the technology of manufacturing many details of the old technique provided for the addition of precious metals and copper in them. Silver, gold and even platinum were added to the board. There is a fairly fair question, how old were these metals, if they are even in the technique? Previously, the device simply could not work. Here are these precious metals and there is a goal of our business. It is "gold" makes the reception of old products favorable and cost-effective.

In addition to precious materials in old TVs there is a mass of non-ferrous metals. These are pieces of copper, aluminum. Select them from parts can be mechanically. Gold and silver, for example, remove only with chemical reactions. About how much aluminum or copper on the TV can be judged by specific model. As for copper, it was used as a winding in transformers. Typically, 500-800 grams of copper can be removed from one TV, and sometimes even more than 2 kg. 1 kg it stands on the market 145 rubles, and aluminum is estimated at 50 rubles.

Reception of Soviet equipment and the allocation of valuable materials and copper from its parts is the basis of our home business. Even if the entrepreneur does not have knowledge to allocate metals, boards can be sold to people who know in radio engineering. Even under such conditions, buying will be profitable.

Below are the minimum prices for some television radio components. That's how much it can cost:

Buying old receivers and TVs is a business. It requires a commercial approach and some organization. In addition to information on the pillars, you can give ads that the purchase of old equipment in newspapers is purchased and on the Internet. Advertising and reception costs can be minimal. You will need some funds on gasoline and car. It should be roomy. In order to save it, it is better to plan the route to make techniques at once from several addresses. The room for equipment can be highlighted in their own apartment. Better if it is a private house. Then the reception can be organized even on the territory. It is necessary to calculate the costs and sales of copper, and precious metals.

Purchase of old radio plants will be then beneficial when the entrepreneur learns to unmistakably set prices for them. How much can earn, depends not only on the state of technology, and from the ability to bargain. As such, there are no places or market prices for TV. Their cost is always determined approximately. The benefit of the owner is the last thing that takes into account when buying is being purchased. A businessman must be sure that he will work on the acquired thing, on selling copper and metals from it. The cost of the old TV can be several dollars and even several hundred conditional units. Japanese TVs, released several decades ago, are very valued. This technique was and remains the most reliable.

It is known that in some radio components, components of electronics in different amounts contain precious metals. The list of dilute and written off devices, various nodes and radio communications blocks with such valuable elements is huge. In the 90s, during the chaos and confusion, when many people had an acute need for money, many have disassembled various written off on radio components electronic devices And thus mined funds for life. Such devices still have some hosts in dachas, in garages, in the yard (outdoors).

About the most common radio components with the content of precious metals

It is no secret that almost all radio components - on boards. Usually in the rear parts of the instruments on aluminum radiators are the CT-812 transistors, the brand Kt-908, the brands of KT-808 and KT-912, the brand KT-809 and the KT-803 brand. On the board, aluminum-based, on the board there are 2T-911B transistors, CT-911.

Switches 11P 3H are attached to the housing, and the resistors of PTP-43, PP3-41, PP3-47 (on the instrument housing) can be inside the metal base unit.

There is an opinion that there are many valuable parts in Soviet TVs. And reality, there you can find only a few condensers of green (km5) and somewhat less often - red-colored (km 6). In such TVs there may be transistors KT-203 (their cost - 5-6 rubles.). On TVs 60-70s, attention should be paid to the lamps.

To get these details, it is necessary to spend a lot of time to disassemble such a large and heavy tv. The same is the case with radioles, lamp receivers, tape recorders. A sufficiently large number of red (less often green) Condenters KMB. As well as yellow and blue ceramic capacitors K10-17 can be found in the VM series video recorders.

Dragmaltal Recordsmen are computing complexes, special electronic devices and PBXs of the production of Soviet times, which are very rare today. It is almost impossible to find them.

When searching for valuable radio components, the main thing is attentiveness. They are sometimes in very inconspicuous blocks and metal boxes. If you caught an eye on the metal box with connectors, you can try to get elements from it with the content of precious metals. Pay attention is also on the details with white contacts. A large number of valuable radio components is in high-frequency generators, frequency meters, frequency synthesizers, electronic voltmeters, oscilloscopes, etc. To remove the desired parts (if there is there), it is necessary to remove the housing.

In the above devices of the first modifications and initial series, there are almost no valuable radio components. Such devices usually have large sizes and weight. They have powerful transformers. Before starting the disassembly, it is better to look at the content table in the instruments of precious metals to understand that you can get from the found device.

Some devices and devices contain a very small amount of precious metals, but are valuable for radio amateurs that will buy it (preferably in working condition).
