flotation can be adapted to a broad range of mineral separations, as it is possible to use chemical treatments to selectively alter mineral surfaces so that they have the necessary properties for the separation. It is currently in use for many diverse appliions, with a few examples being: separating sulfide minerals from silica gangue (and from other sulfide minerals); separating potassium ...

 · Activators also serve to render floatable again minerals which have been temporarily depressed in selective flotation. Sphalerite depressed with cyanide and zinc sulphate can be activated with copper sulphate and it will then respond to treatment like a normal sulphide. Stibnite, the antimony sulphide mineral, responds much better to flotation after being activated with lead nitrate. The ...

02/01/2012 · The pH dependence of kaolinite flotation is also opposite to that of silica, which explains why it is difficult to remove kaolinite in iron ore flotation[29]. For depressantkaolinite interactions, it was found that selective depression of hematite against kaolinite largely depends on strict pH control in iron ore flotation circuits and the ...

PYRITE DEPRESSION: I agree with you. But as per my experience pH play a major role in flotation. Different minerals behave differently at different pH. Lead is floated at low pH. 8 or 9. In cleaner cells pH >9. Cyanide consumption will be less if pH is controlled using instruments and PLC. Pyrite floats at very low pH or gets entrapped during ...
