Copper extraction

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.

Chalcopyrite is a copper iron sulfide mineral. It has been the most important ore of copper for thousands of years.

Copper mining. Introduction.

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 chemical techniques. In this electronic resource, we'll look at the ways in which copper is mined and recovered from its ores.

CHALCOPYRITE (Copper Iron Sulfide)

Chalcopyrite (or copper pyrite), looks like, and is easily confused with Pyrite, FeS2. Chalcopyrite is one of the minerals refered to as quot;Fool's Goldquot; because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule.
