Copper is the most noble of first row transition metals and occurs in small deposits in serveral countries. Ores of copper include chalcanthite (CuSO_(4).5H_(2)O) , atacanite [Cu_(2)Cl(OH)_(3)] , cuprite (Cu_(2)O) , copper glance (Cu_(2)S) , and malachite [Cu_(2)(OH)_(2)CO_(3)] . However, 80 % of the world copper production comes from the ore chalcopyrite (CuFeS_(2)) . The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction. Iron is removed from chalcopyrite as.
