Extraction of Crude Metal from Concentrated Ore

This extraction of crude metal from the ore is done for extracting copper from copper sulphides, lead from lead sulphides and zinc from zinc sulphides. After this step, the oxide of the metals is then reduced by heating them in the presence of carbon. Carbon reduces the oxides to pure metals as it takes away oxygen to form carbon oxides.
