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.
