  • 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 The milling of copper ores as practiced in the larger.
