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

Ore Grinding Mills-Types and Classification Mineral

Jul 15, 2020· In the process of grinding, as in crushing, mineral particles are reduced in size by external forces, mechanical, thermal, hydraulic or electrical. Once the effect of such forces overcomes the internal forces of the solid structure, we have a comminution. Grinding, as a rule, follows crushing which generally ends at a size of 50 mm Read More »Ore Grinding Mills-Types and Classification
