Increasing the Fine Flaky Graphite Recovery in Flotation via . - MDPINov 1, 2017 . Abstract: As the residual flaky graphite ores become miscellaneous and fine, a single treatment technique for the middlings from the flotation process of graphite ore cannot efficiently recover the valuable graphite in the multistage grinding-flotation technology. In the study, the existence form of graphite and.fine grinding and reverse flotation,EFFECT OF THE PARTICLE SIZE ON FLOTATION PERFORMANCE .Grinding liberates mineral grains while flotation separates them into valuable minerals and gangue [10, 11]. Hence, a study was undertaken to know the mean particle size where the recovery and grade are at the best. In this paper, the comparative effect of particle size, on direct and reverse flotation process, on a siliceous.
