  • Pyrite-Gold Recovery in Copper Rougher Flotation Tailings

    the majority of the unliberated gold particles were associated with pyrite as fine inclusions ( 1-3µm) 1 7 . Although higher gold grade (7.6 g/t) was achieved when the copper rougher feed was pre-aerated before flotation the gold flotation recovery (71 ) and kinetics were low. Flotation time (min) 0
