Trithiocarbonates for PGM flotation

Effect on froth phase The presence of stable froth phases is very problematic during froth flotation. Gangue minerals such as talc with non polar or hydrophobic basal planes and polar edges influence froth properties. The polar edges that interact with the water phase and aggregates of these gangue particles increase the interlamellar viscosity.
