Mineral beneficiation and ore dressing
The froth flotation process involves the separation of hydrophobic minerals (minerals that repel water) from hydrophilic (attracts towards the water) gangue. Electrostatic Separation. This separation principle is that different particles with different electrostatic affinities absorb different amounts of current from the surrounding.
