Froth Flotation Copper

The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (cufes 2 ), bornite (cu 5 fes 4 ) and, to a lesser extent, covellite (cus) and chalcocite (cu 2 s).These minerals are concentrated from crushed ores to the level of 1015% copper by froth flotation or bioleaching.
