Silver<\/a> found inside a variety of electronics much more often than others precious metals<\/a>. It surrounds us everywhere, which is why its extraction attracts both those who are just starting out in the Refining<\/a>and experienced miners alike. For beginners it will be useful to learn how to extract silver from radio components in at home<\/a>I'd like to know what kind of sample it might be, and what to do with it next.<\/p>\n\n\n\n

The use of silver in electronics. Technical silver in the USSR<\/h2>\n\n\n\n

Silver conducts electricity and heat better than other metals. It is inert to water, air and some gases. It is used in a wide variety of industries, the list of which is constantly expanding.<\/p>\n\n\n\n

Precious metal<\/a> is used to create jewelry, in the production of contacts for various electrical products, for minting coins, as an investment vehicle, in the manufacture of mirrors, clothing, batteries, in the chemical industry, and in photography. The volume of lunar metal accounted for by the industrial sector exceeds 70% of the global production.<\/p>\n\n\n\n

In the era of the USSR, they did not skimp on silver in the production of radio components. The metal used in this field is called technical. It is a special alloy containing copper, nickel, tin, aluminum, and cadmium as impurities. The amount of additives is not great, usually not more than 0.2% of the total composition. The bulk of it is pure silver.<\/p>\n\n\n\n

\n

Magnetic and non-magnetic samples of technical precious metal are an exception. Here the silver content varies from 60 to 80%.<\/p>\n<\/blockquote>\n\n\n\n

If jewelry metal performs a decorative function, the technical metal must provide electrical conductivity and light reflection.<\/p>\n\n\n\n

There are reference books available online for free, from which you can learn information about the materials that make up electronics.<\/p>\n\n\n\n

List of silver-containing components in electronics<\/h2>\n\n\n\n

The main sources of silver recyclables for refining are devices from the radio and electrical fields. In addition to the lunar metal, devices may contain gold<\/a>, palladium, tantalum, platinum.<\/p>\n\n\n\n

Soviet microcircuits<\/h3>\n\n\n\n

The greatest amount of silver plating is found on chips manufactured before 1990.<\/p>\n\n\n\n

If we compare these Soviet parts with others, they are quite promising for refining. The most lunar metal per 1,000 units of microchips contain:<\/p>\n\n\n\n
