Copper is extracted from the ore, chalcopyrite, CuFeS2 ...

2010-9-28  Percentage copper in chalcopyrite is 63.55/183.54 x 100 = 34.6 %. If the chalcopyrite ore is 0.862 % chalcopyrite then percentage copper present in ore is 34.6 % x 0.862 % = 0.298 % copper. To produce 1.00 Kg of pure copper from an ore containing 0.298 % copper, amount of ore required will be 1.00 Kg x (100/0.298) = 335.57 Kg
