Extraction Of Copper Mining, Concentration, Smelting

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore: The ore is crushed into a fine powder and a suspension is

Why the Extraction of Copper from Chalcopyrite is so

So, extraction of Copper from it becomes very difficult & it is a lengthy process because-(i) It contains many impurities in such a high amount that the percentage of Copper in it becomes only 2-3%. (ii) Copper has more affinity to sulphur than Fe. So, the Cu 2 O formed through roasting of the ore is later converted into Cu 2 S by reacting with Fe 2 S 3. Cu 2 Fe 2 S 3 + O 2 → Cu 2 O + FeO
