The profitable extraction of copper from lowgrade ores requires lowcost processing methods such as in situ or heap leaching (Watling, 2006). Copper (often with precious metals) is predominantly found as chalcopyrite in copper porphyries, ironoxidecoppergold (IOCG) and volcanic massive sulfide (VMS) deposits.

The steps followed for the extraction of copper : Copper is extracted from its ore by heating it with oxygen. Cu_(2)S + O_2 => Cu_(2)O + SO_2 This process of heating of metal below its melting point in the presence of air is called as roasting. The second step is: Auto reduction of copper. Cu_(2)S+Cu_(2)O=> Cu+SO_2 Thus the pure metal copper is obtained from its ore of Copper sulphide.
