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.
