copper sulfate flotation

Jul 09, 2019 (6) Copper-cobalt ore Copper mineral and cobalt-containing pyrite and other cobalt minerals. (7) Arsenic sulfide copper ore The ore has a high content of arsenic, which is mainly in the form of arsenopyrite. Flotation process to solve the problem of copper and arsenic separation, reduce the arsenic content in the copper concentrate as much as

    Investigations into the Recovery of Platinum Group

    Unlike base metal sulfides, the addition of copper sulfate as an activator resulted in a decrease in both the rate of flotation and, especially in the case of PtTe 2 and PtAs 2, in the final recoveries. There were no clear correlations between the observations made of the surface charges of the minerals and their flotation behaviour

    Effect of Copper Sulfate on Zinc Sphalerite Flotation

    Oct 02, 2016 Copper sulfate, when used as an activator in flotation of sphalerite, forms an invisible but physically detectable film of cupric sulfide on the surface of the sphalerite particles, as evidenced by increased electric conductivity, by chemical metathesis, and by the ability to deactivate with solutions of alkali cyanides, which are known as solvents of copper sulfides

    The role of copper sulphate in pyrite flotation

    Jan 01, 1988 Abstract. The role of copper sulphate in the flotation of pyrite has been studied. A survey of a number of pyrite flotation plants using copper sulphate showed that in correct dosages it was able to increase both grades and recoveries. This was confirmed in batch tests

    Apr 11, 2019 In flotation of pyrite with xanthate, butyl xanthate is usually used. Generally, after the activator (copper sulfate) is added to the pulp, the mixed emulsifier of xanthate, pine oil and water can be added at one time, which is better than the multiple addition of the flotation reagent, and the dosage of the flotation reagent will be saved
