  • What Effect Grinding Media has on Selective Flotation of

    The normal practice for processing complex sulphide ore has been to grind with steel balls and/or rods in steel mills before flotation. Little thought had been given to the effect of grinding media on flotation selectivity of copper lead zinc ore. Ore Sample The mill feed for the pilot-plant investigation was from a copper-zinc producing mine in northwestern Quebec.
