phosphate flotation 1983

A process for the separation ofphosphateminerals from aphosphate-carbonate ore, byflotation, wherein a phenol polymer such as a resol or a novolak, which improves the yield and selectivity of thephosphateminerals with respect to the carbonate minerals, is used in addition to a collector agent in theflotation
