Copper Mining and Extraction Sulfide Ores

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore Open pit: 90% of ore is mined by this method Ores near the surface can be quarried after removal of the surface layers The ore is treated with dilute sulfuric acid Get price
