Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
The froth is removed from the top of the cell creating concentrated gold, while the flotation tailings at the bottom of the tank are disposed of. Thanks to froth flotation, miners and refiners are able to extract quality minerals from ore at lower grades than has been previously possible.
