The ore is then ground finely before the copper-bearing sulphide minerals are concentrated by a flotation process that separates the grains of ore mineral from the gangue (waste material). Depending on the type of copper -bearing minerals in the ore and the treatment processes used, the concentrate can contain between 25 and 57% copper.
