  • purification of copper by electrolysis metal extraction

    4a The extraction of copper from copper ores and its purification by electrolysis: How is copper extracted? how is copper purified? What is the state of copper ore reserves? Copper can be extracted from copper–rich ores by heating the ores in a furnace (smelting) and the copper can be purified by electrolysis; However, the supply of copper–rich (high grade) ores is limited.

    History There is evidence that meteorites were used as a source of iron before 3000 bc, but extraction of the metal from ores dates from about 2000 bcProduction seems to have started in the copper-producing regions of Anatolia and Persia, where the use of iron compounds as fluxes to assist in melting may have accidentally caused metallic iron to accumulate on the bottoms of copper smelting.
