refining of copper from chalcopyrite ore

About 34 th of Copper Cu produced in the world has come from Chalcopyrite CuFeS 2, but it is the lowest standard ore of Copper. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.
