2011-7-8 1. Introduction. Wet milling in ball mills followed by flotation is the general practice employed in the beneficiation of copper sulphide ores in which the major minerals of commercial significance typically are chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS) and chalcocite (Cu 2 S). The flotation response of ground minerals can be influenced by the
