True Flotation Versus Entrainment In Reverse Cationic

True Flotation Versus Entrainment In Reverse Cationic The loss of iron-bearing minerals to the tailings, especially in the finest fractions 44 m, is a problem that must be endured due to the depletion of deposits containing high-Fe hematite. The two main mechanisms for iron mineral loss in the froth in reverse cationic flotation are hydrodynamic dragging and true flotation.The loss of iron-bearing minerals to the tailings, especially in the finest fractions 44 m, is a problem that must be endured due to the depletion of deposits containing high-Fe hematite. The two main mechanisms for iron mineral loss in the froth in reverse cationic flotation are hydrodynamic dragging and true flotation.Sep 19, 2017 Due to gradual depletion of high-grade iron ores, there is a need to investigate the treatment of low-grade iron ores. Current procedures are time and cost intensive. Batch laboratory scale reverse cationic flotation was employed to concentrate low-grade Fe ore, found in fluorspar tails in the form of hematite. This study used two types of depressants soluble starch and dextrin and two types ...In terms of flotation, iron ore flotation forms part of the oxide flotation class, as most of the major minerals in the ore are oxides, i.e. alumina, quartz and hematite Liu et al., 2009.
