Copper Mining and Extraction Sulfide Ores

Stage 1: Crushing and grinding The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. (Courtesy of Rio Tinto.) Stage 2: Froth flotation The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of ...

Copper extraction - Wikipedia

If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically then sold to distant smelters, although some large mines have smelters located nearby.
