    Copper is extracted in large amounts from the Earth's crust by mining of sulphide ores and also oxide ores. The procedure of copper processing involves mining and transporting. Oxide ores are generally processed through hydrometallurgy- heap leaching, solvent extraction and electrowinning. The sulfide ores are usually processed using the method of pyrometallurgy- froth floatation, thickening ...

    Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. 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).
