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
