Flotation of Fine Particles: A Review Semantic Scholar

ABSTRACT Literature shows that flotation is highly size dependent and processing both coarse and fine size fractions is problematic. The latter is the subject of the current paper. Fine particles have a relatively high surface area, and therefore more reagents are needed for their processing. In addition, the problem of fine particle flotation is mainly due to their low collision and ...
