Three of the processes introduced above have made great strides in solving these problems for the extraction of copper from chalcopyrite: The GEOCOAT™ Process A heap leaching process that is capable of bioleaching copper concentrates. It does this by coating the concentrate slurry onto a support rock, or substrate material, and stacking this coated material .
Why the Extraction of Copper from Chalcopyrite is so. About 3/4 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 silie, carbonate .
