Separation of mud and sand-flotation. Some concentrators will use a "sand separation" process to achieve the extraction of copper from sulfide ore. After the ore is ground and classified, the mud and sand are flotated separately. Most of the gangue enters the fine mud part and becomes waste ...

Flotation of Sulphide Copper Ore of Sifangjing in Huidong ...

Flotation experimental research is carried out on a certain sulphide copper ore of Sifangjing in Huidong, Sichuan province. The ore exist in the deeper part of ore deposit. Because of the deep burried, the oxidation rate is relatively low. The ore belongs to the typical sulfide ore. For the characteristics of the mine and the scene of the test requirements, the use of direct flotation …Research on Flotation of Copper Sulfide Ore in Yunnan ...Abstract: The ore is the oxide ore of Copper lead and zinc, The ore has high Oxidation rate of Pb,nearly 50%. which contains 3.56% of Pb,3.86% of Zn,0.209% of Cu. The flotation flowsheet consisting of the scene is "Part of the mixed flotation—inhibitor Zn and Pb-Cu mix flotation—Zn flotation—Cu-Pb separation".

The separation of copper sulfide ore minerals from gangue ...

Low grade deposits must be extensively milled to release ore from gangue. Copper sulfide grains milled to 2000 ppm cannot be smelted without releasing gaseous arsenic compounds. Common flotation reagents cannot distinguish between arsenic-bearing enargite (Cu₃AsS₄) and chalcopyrite (CuFeS₂).Molecular modelling and synthesis of a new collector O ...Molecular modelling and synthesis of a new collector O-butyl S-(1-chloroethyl)carbonodithioate for copper sulfide ore and its flotation behavior X.
