Froth flotation - Wikipedia
Froth flotation is applied to a wide range of separations. An estimated 1B tons of materials are processed in this manner annually. Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and
