A review of froth flotation control - ScienceDirect

Froth flotation is a three phase separation process for complex ores based on the manipulation of the difference in hydrophobicity of the solids. Suspended, hydrophobic metal-rich particles are contacted with, and subsequently combine to, air bubbles — whilst the more hydrophilic gangue particles sink and are recovered to the tails stream.
