Controlled Potential Sulphidisation (CPS) Flotation Process

The CPS process achieves this control by utilising a sulphide ion-selective electrode as a control instrument in sulphidisation. The CPS process which uses a selective electrode, enables the sulphide ion concentration in the flotation pulp to be monitored and controlled continuously throughout the stage of sulphidisation.

COARSE AND FINE PARTICLE FLOTATION. Mineral particle size is an important parameter in froth flotation.In 1931,Gaudin,et al. showed that coarse and extremely fine particles are more difficult to recover by froth flotation as compared to intermediate size particles.This was approved by Morrisin 1952.Generally,the flotation recovery and efficiency deteriorate rapidly when operating in the
