Copper mining. From ore to copper. SchoolScience.co.uk

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper minerals

Pyrometallurgy an overview ScienceDirect Topics

Pyrometallurgy works on the thermal treatment of ores and concentrates resulting in physical and chemical transformations in parent minerals and enables the recovery of valuable metals. The treatment produces saleable products (metals) or intermediate compounds/alloys (impure metals) for further processing (refining).

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 water containing a foaming agent which produces a kind of bubble bath. When jets of air are forced up through the bath, the water repellent copper mineral particles are picked up by the bubbles of foam. They float to the surface making a froth.

Copper Mining and Processing Processing of Copper Ores

The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low grade ore, with a

Copper. Copper (Cu) is an extremely useful industrial metal that is ductile (capable of being drawn into wire), malleable (capable of being hammered and molded) and an excellent conductor of electricity (only silver is better). Copper is found in many minerals that occur in deposits large enough to mine.
