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 directsmelting ores are produced, the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger
