About 80% of global copper mine production comes sulphide ores that ore processed using grinding and flotation plants to produce concentrates for smelting. The rest comes from mines using dump or heap leaching, solvent extraction and electrowinning to produce cathode copper. Most copper mines are large, low grade, open pits.

Copper ore is mined from copper rock mountains. After processing, it can be the high grade copper or copper ore sands. The copper ore can be divided into pyrite, chalcopyrite, barite, chalcocite, blue copper, copper blue and malachite etc. It is mainly used in metallurgical industry as the raw material.

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.

Crushing and milling account for just over 50% of copper mine site energy consumption 3 making them a primary target for cost reduction. The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Under-grinding reduces recovery; overgrinding reduces throughput and wastes energy.
