Silver is a universal precious metal, it is used not only for making jewelry, but also in many industries. For jewelry, high samples of silver are suitable, from 830 and above. And for 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 technical silver is worth, since you can earn interest on its sale.
Technical silver
The demand for the precious metal is growing due to the fact that silver does not have time to be mined on the required scale, which requires production, the metal reserves in the ground are becoming less and less. Therefore, investing money and adding silver to an investment portfolio is a profitable business. Even technical silver is in demand in the market.
Where to get technical silver?
Scrap silver is a synonym for technical silver. You can get such a metal yourself, but in small quantities, in such mechanisms:
- radio components;
- connectors;
- resistors;
- capacitors;
- relay;
- batteries.
Switches, transistors, generator lamps also contain a small amount of technical silver. It is used due to its physical and chemical properties, which make contacts tighter and more reliable. The fact is that silver has low resistance, so the metal conducts electricity well. Even on printing and X-ray film there are particles of this precious metal.
Silver scrap from electrical components
Most often, technical silver is subject to remelting. There are rare cases when a 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 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 999. But in practice, no one does this. The functions of silver that are being looked at in the industry are:
- electrical conductivity;
- resistance;
- thermal conductivity;
- light reflection.
IN jewelry production important: ductility, malleability, resistance to mechanical damage. In addition, alloys are added to the ligature of technical silver, which are undesirable for use in contact with the skin, they cause allergies or are radioactive. Therefore, technical silver is cheaper.
The cost of technical silver
Any detail in the mechanism can be silver or coated with a layer of this metal. The price depends on the weight and sample of the product. Usually they buy not one detail, but by weight, and this is called technical silver scrap.
The average cost of such a metal per kilogram reaches five hundred dollars for a 999 sample. Per gram, the price ranges from 11–15 hryvnias or 4–7 rubles. Therefore, it is unprofitable to sell silver in small quantities.
When selling, pay attention to 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, they offer 2-3 rubles or up to 5 hryvnias.
You can sell technical silver to a private person on an ad, as pawnshops are reluctant to accept it and underestimate the price. And many private entrepreneurs can leave the goods without payment, because 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 specifically the types of parts that are accepted for sale.
Study technical silver it is not recommended for beginners, as this market requires well-established contacts between the buyer and suppliers. It is also necessary to know to whom in the future to sell silver for refining and remelting.
Where to get silver ore in The Witcher 2? It is not sold by merchants, I looked at everyone I found.
Where can you get silver ore? The blacksmith does not have enough - there is not enough for a sword, but there is nowhere to get it. How to be? witcher 2. 130.193.51.30.. Where can I get silver ore? The blacksmith does not have enough - there is not enough for a sword, but there is nowhere to get it. How to be?
witcher 2. 130.193.51.30. For more details, see The Witcher 2: Secrets page. Excellent silver witcher sword.
Where can I get the yellow meteorite ore in 3 parts. [Reply] [Cancel reply].
(Minimum 2 characters). The Witcher 2 walkthrough: chapter 1, part 3 of the sword: diamond dust, piece of wood, iron ore, silver ore. So it's better to take the contract from the bulletin board and continue. Taken together!
After reviewing the Witcher 2 blog, I was surprised to find that it did not contain answers to frequently asked questions on the passage in one place.
Q. Where can I find silver ore to forge a silver sword? Hand wrestling is another mini-game in The Witcher 2, along with bones and fisticuffs. Where to get silver ore? Otherwise, two units are not enough for the sword, and the trogov doesn’t even have a mention of it in the square .. The creation of weapons in the first chapter of The Witcher 2 is done by Burnt and Cedric from Bindyuga, and a blacksmith from Flotsam (orders are taken by assistant Berthold Candeleria). You can get silver ore in the cave with nakers, where Malena will lead from Bindyuga..
R "RґRμ RЅR ° ± R№S,Ro SЃRμSЂRμR SЂSЏRЅS Silver has been used by people since time immemorial to disinfect water and heal wounds. Even then, people noticed that water acquires healing properties when it comes into contact with this metal. Even in the records of Herodotus it is mentioned that the Persian king always carried water in silver flasks. In Russia, the healing properties of this metal have also been noticed for a long time. Even the custom of giving a silver spoon “by the tooth” to a child speaks of this. With the appearance of teeth, the child is transferred to complementary foods, and a silver spoon protects him from bacteria. Silver kills all bacteria. Silver utensils were used in temples even before the advent of Christianity, and in rich houses it was generally customary to have silver utensils. Doctors began to use silver during the Russo-Japanese War of 1904. Until the advent of antibiotics, silver was widely used in medical practice. Silver nitrate (lapis) is applied externally in the form of aqueous solutions, ointments for ulcers, erosions, cracks, acute conjunctivitis, and some forms of laryngitis. The protein preparation of silver (protargol) is used as an astringent, antiseptic and anti-inflammatory agent for lubricating the mucous membranes of the upper respiratory tract and as eye drops. A colloidal preparation of silver (collargol) is used for washing purulent wounds, in eye drops, in drops for chronic rhinitis, in the form of ointments in the treatment of certain diseases. Silver is one of the trace elements that are always present in human blood. It is used to accelerate tissue regeneration (with delayed wound healing, gastritis, cystitis, etc.), obesity, connective tissue pathology of various origins, and fluid retention in the body. It also has a regulatory effect on the function nervous system, skin and genitourinary organs, therefore, it can be used for various diseases of these systems, the use of silver for autonomic dysfunctions, hysterical neurosis, and the consequences of a stroke deserves special attention. Today, doctors consider silver not only as a metal that kills microbes, but also as a trace element, which is a necessary part of the tissues of a living organism. Silver trace elements are found in the brain, endocrine glands, liver, kidneys and bones of the skeleton. Currently, silver water can be bought in pharmacies. Making water at home is quite a difficult task. Even if you have a pure silver bowl or jug and fill the vessel with pure water instead of chlorinated tap water, the concentration of silver in the water will not be very high. It is necessary to infuse water in a dark place, since silver ions lose their strength in the light. Such water can be drunk up to 200 ml per day. It is not recommended to obtain silver water by boiling silver items in it, since they must be of a very high standard. It is unlikely that you will find coins made of pure silver. Such coins are issued for anniversaries for collectors. Jewelry silver jewelry is completely unsuitable due to a large number impurities. In industry, silver water is obtained by electrolysis, and the saturation of solutions with silver can be dosed. For those who do not trust pharmacies and want to prepare silver water on their own, it is recommended to use industrial ionizers, the choice of which is quite large, or purchase a special silver filter. It has been proven that water saturated with silver ions stimulates the immune system, normalizes the intestinal microflora due to the antibacterial effect on pathogenic microflora, without causing dysbacteriosis. Silver water is used for a very wide range of diseases. For anal fissures, anal itching, acute and chronic paraproctitis, medicinal enemas with an ionic silver solution in a volume of up to 200 ml once or twice a day (after a cleansing enema), dressings and tampons in wounds are recommended. For peptic ulcer of the stomach and duodenum, chronic gastritis, enterocolitis, take 2 tablespoons three times a day 15-20 minutes before meals for 1-1.5 months. With stomatitis, gingivitis and other inflammatory diseases of the oral cavity - rinses and applications. It is useful to take 1-2 teaspoons inside. With otitis, sinusitis, laryngo-pharyngitis and tonsillitis - irrigation, rinsing the throat; drops and turundas with ionic silver. When rinsing with silver water, it is useful to swallow the last sip so that the solution gets on the back wall. In inflammatory diseases of the female genital organs, silver water is used in the form of irrigation, tampons with a solution. With urethritis, prostatitis and cystitis of various origins - instillations, irrigation. With furunculosis, pyoderma, dermatitis - wet-drying warm dressings. In acute intestinal infections - take a tablespoon every four hours. In inflammatory diseases of the respiratory tract - irrigation (four to five times a day), inhalation. With influenza (for treatment and prevention) - rinse four to five times a day. To stimulate the body's defenses, take 2-3 tablespoons orally three to four times a day 20 minutes before or after meals for 30-45 days. It is very useful to add a few drops of lemon juice to a spoon. Silver water can be successfully used not only for the treatment of influenza, but also for preventive purposes during epidemics. Even if you get sick, the disease will proceed much easier and faster. It is highly recommended to take silver water during severe stress. Silver is a metal with good electrical and thermal conductivity. It lends itself very well to processing and, forged, rolled. It is these above qualities that are the reasons for its very wide application in radio engineering and electrical engineering. In greater quantities it is present directly in massive radio devices, silver-plated products. However, it is quite difficult to extract it from them. This process is quite laborious. If we talk about the possibility of mining it using chemistry, then it should be noted that this is a weakly reactive metal. Nevertheless, it has long been a good source of income for people who understand this business. This article will talk about mining precious metals, in particular silver, from radio components and the percentage of its content in them. The main source of obtaining the precious metal are electronic computers manufactured 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 we take only silver, then it is contained in microscopic doses in radio products and electronics. The largest percentage contains connector contacts, up to 60% silver. As a rule, silver in radio components is not in its pure form, but in an alloy. Taken as a whole, 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. Extracting it from every detail is a rather time-consuming process, since silver is “smeared” on 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 the precious metal in the fusible insert, capacitors, relays based on production in grams from one thousand pieces: There are only two most common options for the presence of silver in radio components: Cupellation, electrical and chemical refining methods are used, In the second case, the simplest and most 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. 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 wire cutters or sawn off. Usually found in pure silver, but sometimes found as alloys. In this case, it is silver from 400 to 900 samples. It is easier to remove it from large structures, but, as a rule, silver is low-grade there, there is a large percentage of impurities. Small parts require more time and effort, but the metal there is clean or 999. Unlike large radio components, chemistry is again used here.
The first option is more laborious both in time and effort. A topic that requires a separate long discussion, since various acids are used here in a certain ratio and temperature regime: hydrochloric, sulfuric, nitric.
