TECHNICAL NOTES 9 FLOTATION - Mineral Tech

The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of a more or less stable froth. The bubbles do not burst when they cross the interface and each one carries a skin of water into the froth phase.

Froth flotation, as a bulk sulphide recovery process, is used to separate the BMS minerals containing the PGE's from the gangue minerals. It is required to optimise the recovery of the BMS minerals in order to maximise the recovery of the PGE's. The flotation process largely depends on differences in hydrophobicity of the various mineral surfaces.
