Copper processingis a complicatedprocessthat begins with mining of theore(less than 1%copper) and ends with sheets of 99.99% purecoppercalled cathodes, which will ultimately be made into products for everyday use. The most common types ofore,copperoxide andcopper sulfide, undergo two differentprocesses, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of theore.

The four major steps in the production of marketablecopperare mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smeltingoresare produced, the bulk of thecopper oremined is concentrated. The milling ofcopper oresas practiced in the larger ...
