Effect of Copper Sulfate on Zinc Sphalerite Flotation

02/10/2016 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

01/01/1988 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. Copper sulphate had no significant effect on the rate of adsorption of potassium n-butyl xanthate (PNBX) onto pyrite. Copper

Copper LPF Leach Precipitation and Flotation Process

16/05/2016 The oxidation-reduction reaction between copper sulphate and metallic iron increases the pH of the pulp to about 3.5-4.0. The copper is precipitated as a very fine copper sponge. An excess of the sponge iron is used so that re solution of copper is avoided. This excess iron carries through the flotation circuit and is recovered by magnetic separation of the final flotation tailing and

Understanding the effect of sulphate in mining-process

01/05/2021 As sulphate ions are always found in high concentrations in process waters, their effects on the flotation of copper, molybdenum and zinc sulphides were investigated in single minerals and ores experiments with complementary mineral surface analysis and particle-bubble detachment studies. It was found that molybdenite flotation was more depressed than chalcopyrite flotation by the presence of

Flotation Depressants Mineral Processing & Metallurgy

12/08/2015 Sodium cyanide is occasionally substituted for lime in the flotation of a sulphide copper ore containing pyrite, since it has a much greater depressing effect on the pyrite than on the copper minerals. Xanthate is generally employed to bring up the copper sulphides, its addition being balanced against that of the cyanide to effect a profitable recovery of the copper with the minimum amount of

Flotation of Copper oxide ore Fodamon Machinery

The reason is that the decrease of PH value after adding ammonium sulfate is beneficial to the increase of HS concentration, the acceleration of sulfidation reaction and the flotation of copper oxide ore. However, when sulfide and oxidize mixed ores are beneficiated, ammonium sulfate can inhibit sulfide minerals when the amount of ammonium sulfate is too large. Therefore, the dosage of

The effect of copper sulphate on froth stability

Froth flotation is a mineral beneficiation process implemented in the recovery of valuable minerals from unwanted gangue material. Copper sulphate is used as an activator in the flotation of base metal sulphides (BMS) as it promotes interaction of collector molecules with the mineral surfaces. It is also used in certain platinum group minerals (PGM) flotation operations in South Africa
