Flotation of Pyrite - 911metallurgist

03.05.2017  The percentage of pyrite or other sulfide mineral in an ore would, to a certain degree, affect the other factors. Hence in these tests the amount of pyrite in the material treated was kept within 15 to 25 per cent. Purity of Water Used. The purity of water used in flotation work may have a very important effect on the results to be obtained; in these experiments ordinary

Can you list the factors affects the floatability of pyrite from refractory low grade ore. I used a Wemco lab flotation cell and aimed on analysing factors like collector dosages (PAX), Activator (Copper sulphate),MIBC , pH and others like pulp density and particle size (70 and 150 microns) .However how these factors affect the floatability of the pyrites from low grade refractory ore.

Pyrite Recovery Mechanisms in Coal Flotation

27.07.2018  Pyrite Recovery Mechanisms in Coal Flotation. In many coal flotation operations, a significant amount of apparently liberated pyrite is seen to report to the froth, thus raising the sulfur content of the clean product and reducing its economic value. Prevention of this unwanted recovery of pyrite is therefore desirable.

Pyrite Depressant - Froth Flotation (Sulphide Oxide ...

I worked on a porphyry copper ore from Philippines before where I found that dithiophosphate worked better in depressing pyrite in the rougher stage. I experienced a copper-gold massive ore type where thionocarbamate seemed to work better. Also, SMBS is a common pyrite depressant. Dithionocarbamates are very selective in copper flotation. It will not float pyrite. Can be used

[Solved] The ore copper pyrite is concentrated by

Copper is extracted from its principal ore Copper pyrites (CuFeS2). The ore is concentrated by froth flotation process. Then, the concentrated ore is roasted in a furnace where reactions remove sulphur and Arsenic gases: S+O2 →SO2 and 4As+3O2 2As2 O3 . The copper pyrite gets converted to a mixture of Cu 2 S and FeS by the reactions given below:

US4904374A - Froth flotation - Google Patents

A method of selectively recovering an arsenopyrite, pyrrhotite or like mineral from a material containing such a mineral and pyrite which includes the steps of providing a slurry of the material, adding a dialkyl (C 3-8 )-dithiophosphate to the slurry, passing a gas through the slurry to cause the mineral to be carried to the surface of the slurry and report in a first float concentrate ...

Flotation Froth - an overview ScienceDirect Topics

In froth flotation, the mineral surface plays an important role in the process of reagent adsorption, which determines the geometry and strength of adsorption, and the difference in properties of mineral surfaces is the premise of mineral separation by flotation. We employed the quantum method to model the galena (100) and the pyrite (100) surfaces and investigate the
