### Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcanthite (CuSO_{4} ,5H_{2}O), atacamite cuprite (Cu_{2}O), copper glance (Cu_{2}S) and malachite However, 80% of the world copper production comes from the ore of chalcopyrite (CuFeS_{2}). The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction. Iron is removed from chalcopyrite as
