Iron ore slimes flotation - ScienceDirect

Oct 01, 2010· Flotation was impaired by slimes coating caused by kaolinite particles. Trahar (1981) investigated the relationship between particle size and collection efficiency in flotation. In summary, the collision efficiency is a function of particle size and the adhesion efficiency is related to both, the mineral hydrophobicity degree, and particle size.
