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 attachment efficiencies with bubbles. Several strategies are proposed in the literature to overcome the problems of fine particle flotation.
