This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning). Advantages of these processes are Much less energy is used than in traditional mining.

Metallurgy process involves the refining of metals and the production of alloys of metals. The impurities present in the ore, which has to be separated in order to obtain desired metal from its ore during the process of extraction, are called gangue. A substance added in the furnace to remove the gangue present in the ore is called flux.
