Copper ore refers to the general term of available natural mineral aggregates containing copper. Copper ore is generally an aggregate composed of copper sulfide or oxide and other minerals, which reacts with sulfuric acid to produce blue-green copper sulfate. The industrial minerals of copper include: natural copper, chalcopyrite, chalcocite, tetrahedrite, chalcocite, malachite, etc. More than 280 kinds of copper bearing minerals have been found, of which only 16 are the main ones. Chalcopyrite (a compound of copper, sulfur and iron) is the main mine in China, followed by chalcocite and bornite.
