Mining Industry Copper Sulfide Ore and Flotation

2019-7-9  3 Summary of the copper mineral flotation process (1) Copper minerals (such as chalcopyrite and covellite) that do not contain iron are similar in floatability. Cyanide and lime have weaker inhibition on them, so a large amount of lime can be added to inhibit pyrite in the separation of copper and sulfur without seriously affecting the floatability of copper minerals.
