Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcanthite (CuSO4 ,5H2O), atacamite cuprite (Cu2O), copper glance (Cu2S) and malachite However, 80% of the world copper production comes from the ore of chalcopyrite (CuFeS2). The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction. Iron is removed from chalcopyrite as
