·Froth flotation was undoubtedly the most innovative and groundbreaking discovery for mining in the 19th century Wills and Finch 2015 Nevertheless it did not last long that scientists recognized its limitations for extremely fine and coarse particles which has remained a long standing unsolved issue in the mineral processing field Gaudin et al 1931
·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
