Metals and Ores ~ Learning Geology

Copper comes from a variety of minerals, none of which look like copper (b in figure above). Geologists have identied a great variety of ore minerals. Many ore minerals are sulphides, in which the metal occurs in combination with sulphur (S), or oxides, in which the metal

Copper

The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 1015% copper by froth flotation or bioleaching.

Copper ore does not contain pure copper, but either a copper sulphur iron compound (chalcopyrite) or a copper sulphur compound (chalcocite). The metal must first be separated from such minerals by means of multi step metallurgic processes. In many cases these processes are so complicated that they account for up to 30 per cent of the metal price.
