The role of copper sulphate in pyrite flotation

1988-1-1  The standard deviation was obtained from a minimum of five tests for each case. The pH for all tests was 4 except Copper sulphate in pyrite flotation 209 for runs 4, 12 and 13 which were done at pH of 9. Copper sulphate, when added to pyrite in the presence of SMBT, resulted in a lower froth height. For coarse particles this effect is even greater.

Effect of Copper Sulfate on Zinc Sphalerite Flotation

2016-10-2  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 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.

The Application of Xanthate in Froth Flotation Process

2019-4-11  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.

Sulfidisation Promotion Effect of Ammonium Sulfate on

This paper presents the sulfidisation promotion effect of ammonium sulfate on the sulfidisation flotation of both malachite and copper oxide ores. Copper oxide ores are commonly difficult-to-float due to its molecular structure, and adding sodium sulfide as activator is necessary; however, its dosage to the flotation pulp must be strictly controlled, as it is also a powerful depressant for
