The final step for the extraction of copper from copper pyrites in Bessemer converter involves the reaction (1) Cu_2S + 2FeO→2Cu + 2Fe +SO_2 (2) Cu_2S + 2Cu2_ O → 6Cu+SO2 (3) 4Cu_2 O +Fe S → 8Cu + 2FeSO4 (4) 2Cu_2 O + FeS → 4Cu + Fe + SO2

Copper is most noble of the first row transition metals and occurs in small deposits in several countries.Ores of copper include chalcanthite (CuSO_4,5H_2O) atacamite (Cu_2Cl(OH)_3) , cuprite (Cu_2O) , copper glance (Cu_2S) and malachite (Cu_2(OH)_3CO_3) . However, 80% of the world copper production comes from chalcopyrite (CuFeS_2) . The extraction fo copper from chalcopyrite involves partial roasting, removal of iron and self reduction. Iron is removed from chalcopyrite as
