extraction processes of copper

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals, the ore is crushed and ground to li

Copper mining and the copper extraction process explained ...

Copper is also extracted from oxidised ores including copper sili es, carbonates and sulphates. Here, the copper ores are crushed and ground as above, but they are then leached with sulphuric acid to produce an impure copper sulphate solution. The solution is purified using solvent extraction and electrode twinning.
