Froth flotation - Wikipedia

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.

Recovery vs. mass pull: The link to air recovery ...

In recent years, developments in control strategy for banks of flotation cells have included process control based on mass pull. Mass pull, or the flowrate of solids reporting to the concentrate, is affected by changes in froth structure and stability which are in turn affected by changes in operating parameters such as air flowrate and froth depth.

Pyrite-Gold Recovery in Copper Rougher Flotation Tailings

recovery (95%) can only be achieved with pyrite flotation (recovery, 93%). A decrease in grind size of the flotation feed from 70 µm to 38 µm and without pyrite flotation stage resulted in a decreased Au recovery (73%) due to depression of pyrite/gold composites (pH 11.5). Therefore, it is crucial to
