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 Openpit 90 of ore is mined using the open pit method Ores near the surface can be quarried after removal of the surface layers The
