mining - COPPER

Mining. Two different mining methods are used for copper ore: Traditional mining – Ore is mined from the ground in an open pit (90% is mined this way) or undergrounds mines. Leaching – ore is treated with diluted sulphuric acid, that trickles through the ore. This then dissolves the copper to form copper sulphate.
