Copper Mining & Extraction Process Flow Chart

The copper oxide minimum minerals are dissolved by the acid to give a blue copper rich solution mainly of copper sulfate. This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper. This process as the advantage of avoiding the smelting and refining ...

to traditional sulphide collectors, flotation plants can now process blends of sulphide and oxide minerals to produce saleable concentrates. Generally copper oxide minerals do not respond well to tradi-tional sulphide copper collectors and require alternative flotation techniques to concentrate the copper oxides. The classical method involves controlled potential sulphidisation (CPS) to ...

Oxide copper minerals are very soluble in the leach solution. Sulfide minerals are rendered soluble by certain bacteria that feed on the sulfide minerals and convert them to soluble sulfates and other soluble forms. This biological action tends to maintain the acidity of the leach solution. Typical operations will leach some areas of the heap, enlarge other sections, and let others rest.
