the review detector has a section for precious metals
right now I looked on the first page selling 112gr jewelry for 30r

Palitch 04/05/2014 - 23:11

Buy some spoons on Avito. By the way, if

goldsmiths are lumping mercilessly for silver
and they there some technical alloy, from the electrical contacts will not charge?

Old Tramp 04/05/2014 - 23:13

At the opening day in Izmailovo. Not the fact that it will be much cheaper.

Yack 04/05/2014 - 23:15

I have never seen such weaving ready for sale. Yes, and in Izmailovo I am far away, I am a Tula.

Alexey Romanov 04/05/2014 - 23:15

announce buyout 1 us dollar

Sherp 04/05/2014 - 23:17

The price of pre-war spoons starts from 40-50 rubles per 1 gram,
the test is true not 925, but 830 + -, if European or 84th, if royal.

Scrap rubles from 30.

But this is in St. Petersburg.

Gentlemen, I have long wanted to make myself a bracelet with weaving Fox's tail, under the order, but the jewelers are breaking mercilessly for the silver from which the product will be. So I was puzzled by the search for scrap silver. Can you please tell me where to get it?
I needed to buy an ingot in the bank. Jewelers lomyat probably not for silver, 30 rubles a gram in mine, but for work

Arlekin_2006 04/06/2014 - 12:01

Silver 999.9 is lighter and cheaper, buy at a bank .. the price is now about 21 rubles per gram for "purity" .. The higher the dollar, the lower the price of silver ... I don't understand this in any way ..

KREPKIY51 04/06/2014 - 12:12

I took 25 rubles per gram at the pawnshop

kkk8814 04/06/2014 - 12:19

Silver 999.9 is lighter and cheaper, buy at a bank .. the price is now about 21 rubles per gram for "purity" .. The higher the dollar, the lower the price of silver ... I don't understand this in any way ..
By the way, Sberbank announces 1800 rubles for a 50g bar.

Nestor74 04/06/2014 - 12:54

Why do you need scrap?
All normal people now take a cleaner at the bank. The price is good. This is the first thing.
Secondly, the jewelers themselves will make the correct ligature. They still have a problem with the crowbar, there is such a test, there is such a thing. And if you bring technical silver, you can also fill your face 😊

Just Pooh 04/06/2014 - 08:18

Ask numismatists for killed 50 kopecks coins of the 1920s.

Yack 04/06/2014 - 10:38

Gentlemen, thank you for your participation. First, I'll go to the jewelers to clarify the prices. And then probably to the bank

LPL 04/06/2014 - 11:11

And if you bring technical silver, they can also fill your face
Enlighten why? Low sample? Or are there many impurities?
There are such! I can sell, the state is true fairy tale!
How much are fabulous coins? At the price of scrap I will buy it right away!

LPL 04/06/2014 - 11:14

I saw the photo. And indeed beauty!

Nikolaich T4 04/06/2014 - 12:22

Strongly said!

Scyth67 04/06/2014 - 13:01

But in fact, what is technical silver, and where, besides a flop, can you use silver contacts?

Grandfather Vasily 04/06/2014 - 14:06


Silver itself is not difficult to find at the prices that the comrades indicated above, there is no need to spoil the spoons with coins for this.

Nestor74 04/06/2014 - 15:18

LPL
Enlighten why? Low sample? Or a lot of impurities ?!
there are a lot of impurities, they don't want to get poisoned again. And casting can behave unpredictably.
Grandfather Vasily
I have a jeweler friend, and I was also going to make myself a piece of silver, but I gave up this idea because the jewelers with whom I talked take the same money for work on gold and silver.
Well, the work is the same.
Here they will order a knife of a certain model from the customer's material: Х12МФ, brass and apple trees, and exactly the same will be ordered from М390, silver and ebony. The works are the same. Do you really ask for the first one half as much as for the second? 😛

Yack 04/06/2014 - 15:44

I went to the jewelers, and they are off today.

Well, except that I really want to pay no attention to the cost.
that's exactly what I didn't see on sale, what I want, so I'll pay for the work as much as they say

36and6 04/06/2014 - 22:06


just don't know how

Ress75 04/07/2014 - 10:33

and I would pour the scrap of silver just from the contacts into an ingot
just don't know how
There is cadmium in contacts. One, two times you can take a risk, but permanently ... You don't want to work with mercury vapor, you need to do the refining, and then work with purity.

gor200766 04/07/2014 - 10:44

autogen to help you ... I melted the silver contacts with an autogen, then flattened the ingot with a hammer - it was a good spoon! 😛

russian-hunter- 04/07/2014 - 11:15

How to distinguish silver spoons and coins from, say, cupronickel (and similar, silver-white)?

chief 04/07/2014 - 11:36

It is very difficult to distinguish from cupronickel dishes, because cupronickel dishes are silver ... True, the MSC is usually written 😊

36and6 04/07/2014 - 11:52

The blowtorch won't take it, nobody tried it?

gor200766 04/07/2014 - 13:33

autogen is cool, I have not.
The blowtorch won't take it, nobody tried it?
I also don't have an autogen, a blowtorch gives only 750%, and the melting temperature of silver is above a thousand ... Therefore, put your hands on your feet, take the contacts and go to a service station or a construction site. By the way, he gave the silver melted by autogen to the jeweler, who said that the silver was almost pure, about 925 tests (at high temperatures, all the additives in technical silver burn out and form a slag crust on top, which can be carefully removed with tweezers). The jeweler cast me such a medallion from an ingot (9 grams).

Alexander = - 04/07/2014 - 13:45

Grandfather Vasily
the jewelers with whom I spoke take the same money for work on gold and silver ...
... But it’s not worth it.
I, too, was somehow puzzled where to attach my silver crowbar. Have you thought about making a signet? talked to the jewelers. everything, as Grandfather Vasily told.
figured that for the same money you can ready product take. and since the seal is not the goal itself, my scrap remained unclaimed, like a suitcase without a handle: it's a pity to throw it away.

------------------
Anyone who "knows how it will be better for me" I write in my notebook on the list "shoot first."

gor200766 04/07/2014 - 14:02

Anyone who "knows how it will be better for me" I write in my notebook on the list "shoot first."
and write me down 😛, because silver scrap, which you don't know what to do with, will do for bolsters ...

you say feet into hands.

if you want to pick up "heavy metals" then go ahead as you are advised.
contacts are available - magnetic and non-magnetic.
their sample is different from 500 to 800
and that only spectral analysis can show that there is no doubt.
The one ahead, oncology is your diagnosis.

Most do not have an autogen and a construction site next to it, there is no muffle oven and no desire to buy it, but many have an old microwave.
And people have accumulated many tons of contacts around the country and no one knows what to do with them due to the economic unreasonableness of working with home melting of metal.

The video is valuable because the person showed that there is a completely affordable way.
I personally meet this variant of heating and melting metals for the first time.

vegra 04/07/2014 - 22:43

Contact to contact strife
eat out of pure
there is a bimetallic base copper and a splash of pure silver on top
there is an alloy, it seems, with tungsten ... the inventor was awarded a state prize for this.
And they are attached in different ways
mechanically like rivets
welding
and soldered ... in the solder just any poisonous crap can be

Silver is a versatile precious metal, it is used not only for the manufacture of jewelry, but also in many industries. High samples of silver, from 830 and above, are suitable for jewelry. And for the industry, the amount of copper or other impurities in the alloy does not matter. Therefore, such silver, which is most often found in radio components and other mechanisms, is called technical. Investors are interested in the question of how much is technical silver, since it is possible to earn interest on its sale.

Technical silver

The demand for precious metal is growing due to the fact that silver does not have time to be mined in the required scale, which requires production, the reserves of metal in the ground are becoming less and less. So investing money and adding silver to an investment portfolio is a profitable business. Even technical silver is in demand in the sales market.

Where can I get technical silver?

Silver scrap is synonymous with technical silver. You can get such metal yourself, but in small quantities, in such mechanisms:

  • radio parts;
  • threads;
  • resistors;
  • capacitors;
  • relay;
  • batteries.

Switches, transistors, oscillator lamps also contain a small amount of technical silver. It is used due to its physical and chemical properties, which make the contacts tighter and more reliable. The fact is that silver has low resistance, so the metal conducts electricity well. Even printing and X-ray films contain particles of this precious metal.

Silver scrap from electrical parts

Most often, technical silver is subject to melting. There are rare cases when precious metal gets into radio components after refining, that is, cleaning, and is already contained in pure form... Of course, such contacts will improve current conductivity, but they are more expensive.

In fact, technical silver differs from jewelry only in its breakdown, and even then not in all cases. This phrase simply indicates the purpose for which the precious metal is used. Theoretically, jewelry can be made from technical silver of 999 assay value. But in practice, no one does this. Silver functions that are being looked at in the industry:

  • electrical conductivity;
  • resistance;
  • thermal conductivity;
  • light reflection.

IN jewelry production important: plasticity, malleability, resistance to mechanical damage. In addition, alloys are added to the technical silver ligature, which are undesirable to use in contact with the skin, they cause allergies or are radioactive. Therefore, technical silver is cheaper.

Technical Silver Cost

Any detail in the movement can be silver or coated with a layer of this metal. The price also depends on the weight and sample of the product. Usually they buy not one part, but by weight, and this is called scrap technical silver.

The average cost of such metal per kilogram reaches five hundred dollars for a 999 test. Per gram the price ranges from 11-15 hryvnia or 4-7 rubles. Therefore, it is not profitable to sell silver in small quantities.

Pay attention when selling whether your parts are magnetic or not. This also plays a role for the buyer. Magnetic silver is not used in all industries. Therefore, its cost is cheaper. For a gram of magnetic silver offer 2-3 rubles or up to 5 hryvnia.

It is possible to sell technical silver to a private person according to an advertisement, since pawnshops are reluctant to accept it and lower the price. And many private entrepreneurs can leave the goods without payment, since they work illegally. There is a demand for such silver in the electrical, medical, film, photo and radio industries. Choose wholesale buyers and compare prices. Many of them indicate the specific types of parts that are accepted for sale.

It is not recommended for beginners to deal with technical silver, as this market requires established contacts between the buyer and suppliers. And you also need to know who will sell silver for refining and smelting in the future.

Silver is a metal with good electrical and thermal conductivity. It lends itself very well to processing and, forging, rolling. It is these above qualities that are the reasons for its very wide application in radio and electrical engineering.

It is present in large quantities directly in massive radio devices, silver-plated items. However, it is quite difficult to extract it from them. This process is quite time consuming. If we talk about the possibility of extracting it using chemistry, then it should be noted that it is a weakly reactive metal.

Nevertheless, it has long been a good source of income for people who are versed in this matter. This article will tell you about the extraction of precious metals, in particular silver, from radio components and the percentage of its content in them.

The main source of obtaining precious metal is electronic computers produced in the Soviet years, various control units, again Soviet, radio devices.

It should be borne in mind that most of the various precious metals are contained in Soviet civilian and military devices. If you take only silver, then it is contained in microscopic doses in radio products and electronic elements.

The largest percentage contains connector contacts, reaching 60% silver. As a rule, silver in radio components is not in pure form, but in an alloy.

Generally speaking, there are few types, types of parts and elements containing this precious metal. Relay contacts, capacitors, diodes, transistors, resistance contacts and connectors - these are the radio products richest in this metal.

It is a rather laborious process to extract it from every part, since the silver is "smeared" over the electronic scrap.

Therefore, its removal at home is possible only from certain types of radio parts.

We provide more specific information on the content of precious metal in a fuse-link, capacitors, relays based on production in grams of one thousand pieces:

  • VP1-1 15.611gr;
  • K15-5 29.901 g;
  • K10-7V 13.652 gr;
  • RES6 - 157 gr;
  • RSCh52 - 688 gr;
  • RCMP1-132 gr;
  • RVM - 897.4 gr.

There are only two most common options for the presence of silver in radio components:

  1. In a thin layer applied to the outer or inner part of the part.
  2. Contained in almost pure form.

The first option is more time consuming both in time and effort. A topic that requires a separate long conversation, since various acids are used here in a certain ratio and temperature regime: hydrochloric, sulfuric, nitric.

Methods of cupelling, electric and chemical refining are used,

In the second case, the most simple and accessible to any student, the case is removed from the parts and the silver contacts are simply cut off. This process is quite time consuming, but simpler than the first one.

The highest silver content in radio components: connectors, contact relays, starters, ceramic capacitors, radio lamps. But most of all, its content is in relays and Soviet microswitches.

In one relay, you can get 2-3 grams of pure 817 silver. In massive electrical contacts, it is bitten off with nippers or sawed off.

Pure silver is commonly found, but is sometimes found as alloys. In this case, it is silver from 400 to 900 standard. It is easier to remove it from large structures, but, as a rule, silver there is of low grade, there is a large percentage of impurities.

Small parts require more time and effort, but the metal is also pure or 999. Unlike large radio components, chemistry is again used here.

Where to get silver ore in The Witcher 2? Not for sale at merchants, I looked at everyone I found.

Where to get silver ore? The blacksmith has little - not enough for a sword, but nowhere to get it. How to be? witcher-2. 130.193.51.30 .. Where can I get silver ore? The blacksmith has little - not enough for a sword, but nowhere to get it. How to be?
witcher-2. 130.193.51.30. See more details on the page The Witcher 2: Secrets. An excellent silver witch sword.
Where can I get the yellow Meteorite Ore in 3 parts. [Reply] [Cancel reply].

(2 characters minimum). Passage of The Witcher 2: chapter 1, part 3 of the sword: diamond dust, a piece of wood, iron ore, silver ore. So it's better to take the contract from the bulletin board and continue. Together!
After looking through the blog of The Witcher 2, I was surprised to find that it never collected in one place the answers to frequently asked questions on the passage.
Q. Where can I find silver ore to forge a silver sword? Hand wrestling is another mini-game of The Witcher 2, along with bones and fistfights. Where can I get Silver Ore? And then two units are not enough for a sword, but the trogovtsa has no trace of it on the square .. In the first chapter of The Witcher 2, Burnt and Cedric from Bindyuga, and a blacksmith from Flotzam (orders are taken by assistant Berthold Candeleria) are engaged in the creation of weapons in the first chapter of The Witcher 2. Silver ore can be taken in the cave with nakers, where Malena from Bindyuga will lead ..
