Purification of Metals - Big Chemical Encyclopedia
Most copper is mined in the form of the ores chalcopyrite (CuFeS2), chalcocite (CU2S), and malachite (Cu2C03(0H)2). The sulfides are most abundant and yield copper metal when heated strongly in the presence of oxygen. In Section 17.6 we discussed applications of electrolysis in the extraction and purification of metals from their ore sources.
