    This ore processing plant is for the flotation of 2 base metals (Cu/Pb/Zn/Co/Ni/etc.) which may or may not contain precious metals. These ore deposits are called polymetallic by geologists and metallurgists. This system allows you to recovery by way of differential or sequential flotatio, the sulphide metals in 2 separate concentrates. Examples include: Copper, Lead, Zinc, Cobalt, Nickel
