Copper Mining. The following gives an overview of how copper is extracted from its ore and converted into pure metal. Mining The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open-pit – 90% of ...
