Copper was discovered in prehistoric times, and was one of the first metals that man began to use for practical purposes instead of stone. The Latin name "Cuprum" came from the name for the island of Cyprus, where, as early as the third century BC, copper was already mined and smelted. There are mines that have been found on Russian territory that are believed to be several thousand years old. In the 18th century, dozens of copper smelting works were founded in the Urals and in the Altai region. Metallurgy in the Far North began to develop in the late 19th century.
Electrical engineering, electronics, telecommunications and construction are the most significant areas of copper consumption. With its high thermal and electrical conductivity, copper finds wide application in production of cables and conductors, electric generators, radio equipment and telephone equipment. In refrigeration engineering copper is used in manufacturing of heat exchangers of cooling devices; in chemical industry it is applied in manufacturing of vacuum devices. Copper is in demand in construction of power lines and communication lines. Copper pipes are used in gas, heat and water supply systems. Roof coverings and finishes are made of copper, softness and malleability of copper makes it possible to use it in manufacturing of cookware and artistic products.
