The PGMs are separated from the ore by flotation. In this process unwanted minerals are also recovered. Talc is naturally hydrophobic and its flotation is depressed by polymeric depressants. Chromite is considered to be hydrophilic and in general, its recovery follows water recovery as expected from the mechanism of recovery by entrainment. In some cases however, it has been reported that ...
