How is copper extracted from the ground
WebCopper is also extracted from oxidised ores including copper silicates, 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. Can copper be recycled? WebCopper extraction refers to the methods used to obtain copper from its ores.
