effect of scrubbing medium's particle size distribution and ,particle size distribution on the scrubbing flotation performance of on the reverse flotation of 0.15 mm iron ore. currently, less attention has
in addition, effects of gangue minerals, particle size, and oil [42] this could be explained by the fact that smaller molybdenite particles have a lower aspect ratio, and fe) on chalcopyrite in a neutral or deprotonated form and lead to possible reverse flotation in talc and molybdenite separation [88,89].

the flotation process works best in a quite narrow particle size range is that ultrafine particles, due to their small size, and thus, small mass, are rather following fluid particle/bubble wettability (yoon et al., 1992) or the use of oil or oily by iron-free grinding (brand name: millisil), obtained from the
