flotation process of cus ore

Flotation of Chalcocite (Cu 2 S) Chalcocite (Cu 2 S) and chalcopyrite (CuFeS 2) are the two most commonly floated copper sulphide minerals. Bornite (Cu 5 FeS 4) and covellite (CuS) and energite (Cu 3 AsS 4) are normally present in lesser quantities. The complete flotation of chalcocite is achieved between ph = 1 to ph = 10 with ethyl xanthate

    Copper ore may be separated from crude ore using a flotation pro-cess that takes advantage of the physical (as opposed to chemical) properties of small copper ore particles. To maximize the copper yield, pH control is necessary in the flotation tanks. The copper flotation process Crushed ore, along with water and

    Jul 09, 2019 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
