Copper mining and the copper extraction process

Copper 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.

3.3.4 Copper extraction :: GCSE notes

2015-6-17  Traditional methods. Copper is usually sourced from copper-rich ores in two main methods; Copper can be smelted in a furnace by heating it with air to produce crude copper metal; for example, chalcocite is an ore of copper (I) sulfide, which reacts with oxygen to extract the copper: Cu 2 S (s) + O 2 (g) → 2Cu (s) + SO 2 (g) Copper ore can also be reacted with sulfuric acid to produce copper ...
