top one chalcopyrite flotation separation 1 Chalcopyrite CuFeS2 Chalcopyrite including Cu 34.57 is the most common copper mineral in Chinas copper mines has good buoyancy. Chalcopyrite is not easily oxidized and it can maintain natural floatability for a long time in neutral and weakly alkaline pulps. However in a strongly alkaline pHgt10 slurry since the surface is eroded by OH- a hydrophilic iron hydroxide film is ...
