    Copper mining and the copper extraction process …

    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. Can copper be recycled?
