Copper Mining and Processing: Processing of Copper Ores ...

Copper Mining and Processing: Processing of Copper Ores. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit.

Copper Concentrate Enrichment Process - 911metallurgist

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps. Some ores have associated problems such as chalcocite-coated pyrite and are difficult ...
