Copper Concentration Operation

About 80% of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence:

1. Beneficiation by froth flotation of ore to give copper concentrate(Optional partial roasting to obtain oxidized material or calcines).

2. Two-stage pyrometallurgical extraction: smelting concentrates to matte; converting matte by oxidation to crude copper.

3. Refining the crude copper, usually in two steps: pyrometallurgically to fire-refined copper; electrolytically to high-purity electrolytic copper.

Copper Beneficiation Plant

The copper ore coming from the mine must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue. Therefore, in the first step the lumpy ore is crushed and milled into fine particles(< 100 μm) to liberate the individual mineral phases.

Typical equipment for crushing to about 20 cm are gyratory and cone crushers. Then wet grinding in semi-autogenous rod or autogenous ball mills takes place. Size classification takes is performed in cyclones. In the next step of beneficiation, valuable minerals and gangue are separated by froth flotation of the ore pulp, which exploits the different surface properties of the sulfidic copper ore and the gangue.
