Jan 14, 2019· After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic. The mixture is then bathed in water along with a foaming agent, which encourages frothing.
Copper | Geoscience Australia
The ore is then ground finely before the copperbearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60% copper.
