Copper is the most noble among the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcopyrite (CuFeS_(2)), cuprite (Cu_(2)O), copper glance (Cu_(2)S) and malachite [CyCO_(3).Cu(OH)_(2)]. 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 ironand self-reduction.
