copper sulfate flotation

HYDROMETALLURGICAL PRODUCTION OF COPPER FROM FLOTATION CONCENTRATES By J. R. Cobble,1 C. E. Jordan,2 and D. A. Rice3 ABSTRACT Dissolution of chalcopyrite with acidified ferric sulfate produces a sulfur layer on the unreacted chalcopyrite surface that interferes with further dissolution. The U.S. Bureau of

    US10005088B2 - Flotation of sphalerite from mixed base

    The main objective of the invention was to develop a new flotation collector that could eliminate or reduce the amount of copper sulfate used in the flotation of sphalerite. Different series of collectors such as cupferrons, arylhydroxamic acids and amino mercaptans or amino thiols were synthesized and tested. Amino mercaptans/aminothiols were found to be very effective in floating sphalerite

    Copper Sulfate | Chemistry Reagent Supplier | Kangtai

    Copper sulfate is a massive crystal with irregular shape and size. The color can be dark blue or light blue which is translucent. It is quite fragile so that it is easy to be cracked and dissolve into the water. The copper sulfate is odourless, bitter in taste and astringent. CuSO 4 5H 2 O is very stable under normal pressure and temperature

    The Application of Xanthate in Froth Flotation Process

    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

    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

    Studies on flotation kinetics also confirmed the improved selectivity attained by using copper sulfate and a CMC. The selectivity index (SI) for sphalerite, with respect to pyrite, improved from 0.88 to 2.35 when copper sulfate was added, and that for nonsulfidic gangue increased from 1.93 to 6.29 when CMC was added

    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
