Copper mining. Introduction.
These mines have now closed and today the biggest copper mines are in Chile and North America. These produce many thousands of tonnes of copper ore per year. The main ores of copper are: chalcopyrite bornite malachite. The ores are extracted by either traditional mining open pit or underground or by leaching. The copper is then recovered using physical and
