    Mined ore with a copper grade of more than 0.40% is sent to the crushing circuit, where the size is reduced by approximately 85%. The crushed ore then passes through rod and ball mills, to produce a fine powder. The finely ground powder is mixed with water and sent to flotation cells to produce a copper concentrate.

    Apr 11, 2017 Copper Ore Processing Methods. The four major steps in the production of marketable copper are 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-smelting ores are produced, the bulk of the copper ore mined is concentrated.
