Froth flotation

2018 10 27&ensp·&enspFroth 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.

Role of Bubble Size in Flotation of Coarse and Fine

2003 6 1&ensp·&enspThe low flotation recovery of fine particles is mainly due to the low probability of bubbleparticle collision, while the main reason for poor flotation recovery of coarse particles is the high probability of detachment of particles from the bubble surface.
