Recovery of coarse particles in the froth phase – A case ...

2013-5-1  1. Introduction. The ability to separate minerals by froth flotation is strongly dependent on the particle size. For metallic ores, particles respond well to flotation up to 100 μm, but above this size the recovery rate declines significantly with increasing particle size (Jowett, 1980, Trahar, 1981).The reasons for poor flotation of coarse particles are well-established and include ...
