Extraction of Crude Metal from Concentrated Ore

10-12-2020  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.

You will find that the ores of many metals are oxides. This is because oxygen is a very reactive element and is very abundant on the earth. i) Metal of low reactivity: These metals are mostly found in free states. Eg: Gold, silver, platinum, copper. ii) Metal of medium reactivity: These metals are found mainly as oxides, sulphides or carbonates.
