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. Copper is chemically extracted from crude ores by first roasting it at temperature up to 500 C. for 90 minutes, then treating it with ammonium salt followed by leaching with sulfuric acid to obtain a soluble copper mass for further purification.

Sulphide, oxide, and mixed ore are fed to separate mineral processing circuits tailored for recovery of the dominant copper minerals in each. After comminution to a target grind size of 80% passing 150 m, each ore type is subjected to flotation to recover the copper sulphide minerals (chalcopyrite, bornite, chalcocite, covellite). Method 2 By heating copper sulfide ores to produce copper oxide which is then treated with sulfuric acid to form copper sulfate. Method 3 By slow leaching in air of piles of low grade ore. Bacterial action is sometimes employed to hasten the process. A solution of copper sulfate drains away from such heaps.
