Copper Mining and Extraction | Copper Mining Processing

Copper is extracted in large amounts from the Earth's crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate, carbonate or sulphate ores.

Copper

This mechano-chemical process can leach 97-99% copper directly on site, from concentrates as low as 5% copper in less than six hours. This makes it feasible for you to produce cathode copper from concentrate directly at the site rather than to sell the concentrate to a smelter. The ROL process can even leach copper from arsenic-ladden concentrates.
