Mt Isa is one of the world's largest underground mines and one of the few places in the world where copper silver lead and zinc are found and mined in the same area.
As in all mining operations the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite) the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals.
