Minimization of the carbonate content of talc pre-concentrate by multistage flotation was optimized in the laboratory through natural floatability of the talc and application of a selective carbonate depressant.
Flotation is conducted at high pH levels often times greater than 11 using lime to ensure good depression of sulphide minerals, particularly iron sulphides and copper. Other depressants used include cyanide and Nokes reagent (thiophosphorous or thioarsenic compounds).
