Silver has been used by people since time immemorial to disinfect water and heal wounds. Even then, people noticed that water acquired healing properties when it came 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 Rus', the healing properties of this metal have also been noticed for quite a long time. Even the custom of giving a silver spoon “for a tooth” to a child speaks of this. With the appearance of teeth, the child is transferred to complementary foods, and the silver spoon protects him from bacteria.

Silver kills all bacteria. Silver dishes were used in temples even before the advent of Christianity, and in rich houses it was generally customary to have silver dishes.

Doctors began to use silver during the Russo-Japanese War of 1904. Until the advent of antibiotics, silver was very widely used in medical practice.

Silver nitrate (lapis) is used externally in the form of aqueous solutions, ointments for ulcers, erosions, fissures, acute conjunctivitis, and some forms of laryngitis. A 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 always present in human blood. It is used to accelerate tissue regeneration (with delayed wound healing, gastritis, cystitis, etc.), obesity, connective tissue pathologies 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, can be used for various diseases of these systems, special attention The use of silver for autonomic dysfunctions, hysterical neurosis, and the consequences of a stroke deserves to be used.

Today, doctors consider silver not only as a metal that kills microbes, but also as a trace element, which is a necessary component of the tissues of a living organism. Microelements of silver are found in the brain, endocrine glands, liver, kidneys and skeletal bones.

Currently, silver water can be bought in pharmacies. Preparing water at home is a rather complicated matter. Even if you have a sterling silver bowl or jug ​​and fill the vessel with clean, not 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 potency in light. You can drink up to 200 ml of this water per day. Produce silver water by boiling it silver products not recommended as they must be of very high standard. It is unlikely that you will have coins made of pure silver. Such coins are issued for anniversaries for collectors. Jewelry silver jewelry completely unsuitable due to large quantity impurities. In industry, silver water is obtained by electrolysis, and the saturation of solutions with silver can be dosed. Those who do not trust pharmacies and want to prepare silver water themselves are 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 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 silver ionic solution in a volume of up to 200 ml are recommended once or twice a day (after a cleansing enema), bandages and tampons for wounds.

For gastric and duodenal ulcers, chronic gastritis, enterocolitis, take 2 tablespoons three times a day 15-20 minutes before meals for 1-1.5 months.

For stomatitis, gingivitis and other inflammatory diseases of the oral cavity - rinses and applications. In this case, it is useful to take 1-2 teaspoons orally.

For otitis, sinusitis, laryngo-pharyngitis and sore throat - irrigation, gargling; drops and turundas with ionic silver. When rinsing with silver water, it is useful to swallow the last sip so that the solution reaches the back wall.

For inflammatory diseases of the female genital organs, silver water is used in the form of irrigation, tampons with solution.

For urethritis, prostatitis and cystitis of various origins - instillation, irrigation.

For furunculosis, pyoderma, dermatitis - wet-dry warm bandages.

For acute intestinal infection, take a tablespoon every four hours.

For inflammatory diseases of the respiratory tract - irrigation (four to five times a day), inhalation.

For flu (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 to treat influenza, but also for preventive purposes during epidemics. Even if you get sick, the illness will progress much easier and faster. It is highly recommended to take silver water during severe stress.

Getting pure silver at home is real!

To obtain pure precious metal A technology for its purification from impurities has been developed. It was called refining. During this procedure, the metal goes through several stages of processing, which results in silver, gold or platinum of a given purity.

It is considered an industrial process, but nowadays white metal refining can be done at home. Typically used for cleansing:

• jewelry;
• sludge from its electrical cleaning;
• technological silver-containing scrap;
• “silver foam” from waste from lead factories.

Refining consists of three parts: diluting the silver in nitric acid, solidifying the metal and fusing it, and refining itself by electrolysis (electrolytic method).

Now let's talk about everything in order.

Available tools and materials

To carry out this at home and obtain metal without impurities, you need a little knowledge of chemistry (at the level high school), as well as the following materials:

• nitric acid 68.8%;
• deionized water;
• glass container;
• scales;
• quartz and brass sticks;
• titanium crucible (container for fusion);
• copper tubes or any other copper products;
• coffee filters;
• any power supply;
• plastic lemonade bottle;
• stainless steel fork and electrical tape;
• tea filter;
• insulation tube.

Metal dissolution

The process begins by mixing acid and water. The acid must be diluted with water in a 1:1 ratio, stirred with a quartz stick and silver should be added to the mixture at the rate of 50 g of silver per 1 liter of water.

Attention: acid pours into water, and not vice versa, in addition, you must wear gloves and protective glasses. During the chemical reaction, the solution should turn blue. The process can take from several hours to days. The result is silver nitrate.

Silver cement

The task of the next stage will be to obtain metal from silver nitrate. For this you will need copper. Since silver nitrate has a blue tint, it already contains copper. The lighter the solution, the better it is. You can use ordinary pipes as a source of copper. Old water pipes will do, they just need to be cleaned of dirt and deposits.

Pieces of copper pipes are placed in a silver solution. Copper serves as a catalyst and speeds up the process. The pipes quickly become covered with a silver coating – cement. Periodically, they need to be removed and the cement shaken into a jar of solution. Copper pipes gradually dissolve, releasing copper to silver nitrate. If there are not enough of them, new ones should be added.

The pipes can be left in this position for 1-2 days, periodically checking them and making sure that no foreign objects get into the container. The process ends with the formation of a sediment of silver cement at the bottom of the container and the cessation of the reaction.

The solution must be filtered. To do this you will need a funnel and several coffee filters. The sediment must be washed at least 5 times with clean water. Moisture evaporates from the remaining cement (you can wait until it evaporates naturally).

Do not rush to throw away the solution after filtration: it still contains silver. Add some table salt to it and keep it aside. After some time, silver chloride will appear in the container.

Silver cement, consisting of crumbs and dust, must be collected into a single piece. This is done by heating it in a crucible. You need to heat it evenly and slowly, otherwise the silver dust will fly in different directions. The silver obtained at the second stage at home is not pure; it can be conventionally designated as 980 fineness. The bar will undergo further purification by electrolysis.

Highest standard silver

In the final part of the refining, you need to build an electrolytic bath. The bottom of a cut lemonade bottle can be used as a container. The height of the container must be such that it can hold at least 1 liter of solution.

A block made from silver cement is placed in a tea filter. A ribbon of pure silver is welded to it in advance and clings to the middle of a brass stick. It is necessary to put insulation on it, since it will play the role of an anode. The stick is threaded through the edges of the tea filter and placed above the bathtub.

The fork handle is wrapped with electrical tape, and its end is bent so that the fork can be hung on the edge of the bath. The result was a miniature electrolytic container.

The solution with silver nitrate is diluted with distilled water in a 1:1 ratio and poured into the bath. The liquid should not touch the joint between the silver bar and the tape, otherwise the metal will dissolve.

The plug is placed in the bathroom, a “minus” cable goes from the power supply to it, and a “plus” cable goes to the brass stick. Make sure that the current voltage is no more than 4-8 W and the power is 5 A.

The reaction begins immediately: the walls of the bath are covered with silver crystals, and the bar gradually becomes smaller. The tea filter is used to collect suspended matter and debris. The crystals should not reach the tea bag, otherwise a short circuit will occur.

Place the electrolyte solution in a container. The resulting crystals need to be washed several times in water, dried and fused into one piece, as was previously done with silver cement.

The refining is completed, and as a result you have received, from which you can make original jewelry.

Silver is a metal with good electrical and thermal conductivity. It lends itself very well to processing and is forged and rolled. It is these above-mentioned qualities that are the reasons for its very wide use in radio engineering and electrical engineering.

IN more present directly in massive radio devices and silver-plated products. However, it is quite difficult to extract it from them. This process is quite labor-intensive. If we talk about the possibility of extracting it using chemistry, it should be noted that it is a weakly reactive metal.

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

The main source of precious metal production is electronic computers produced 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 electronic elements.

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

If we take it in general, 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 each part is a rather labor-intensive process, since the silver is “smeared” on the electronic scrap.

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

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

• VP1-1 15.611g;
• K15-5 29.901 g;
• K10-7V 13.652 g;
• RES6 - 157 g;
• RSCh52 - 688 g;
• RKMP1-132 gr;
• RWM - 897.4 g.

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

1. Applied in a thin layer to the external or internal part of the part.
2. Contained in almost pure form.

The first option is more labor-intensive 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 conditions: hydrochloric, sulfuric, nitric.

Methods of cupellation, electrical and chemical refining are used,

In the second case, the simplest and most accessible to any schoolchild, the body is removed from the parts and the silver contacts are simply cut off. This process is quite labor-intensive, but simpler than the first.

The highest silver content is 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 sawed off.

Commonly found pure silver, but is sometimes found in the form of 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, the silver there is of low quality and contains a large percentage of impurities.

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

Silver is a universal precious metal; it is used not only for making jewelry, but also in many industries. Suitable for jewelry making high samples silver, from 830 and above. But 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 interest can be earned by selling it.

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 that production requires, and the reserves of the metal in the ground are becoming less and less. Therefore, investing and adding silver to your investment portfolio is a profitable business. Even technical silver is in demand on the market.

Where can I get technical silver?

Scrap silver is a synonym for technical silver. You can get such metal yourself, but in small quantities, in the following mechanisms:

• radio components;
• cuts;
• resistors;
• capacitors;
• relay;
• batteries.

Switches, transistors, and generator tubes 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 printing and X-ray films contain particles of this precious metal.

Scrap silver from electrical parts

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

In fact, technical silver differs from jewelry silver only by its breakdown, and then not in all cases. This phrase simply indicates the purpose for which the precious metal is used. Theoretically, jewelry can be made from 999 sterling silver. But in practice no one does this. Functions of silver that industry pays attention to:

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

In jewelry production, the following are important: plasticity, malleability, resistance to mechanical damage. In addition, alloys are added to the technical silver ligature that 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 part in the mechanism 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 technical silver scrap.

The average cost of such metal per kilogram reaches five hundred dollars for 999 samples. Per gram the price ranges from 11–15 hryvnia or 4–7 rubles. Therefore, selling silver in small quantities is unprofitable.

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 hryvnia.

You can sell industrial silver to a private person through an advertisement, since pawnshops are reluctant to accept it and lower 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 price offers. Many of them indicate specifically the types of parts that are accepted for sale.

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