True flotation versus entrainment in reverse cationic

True flotation versus entrainment in reverse cationic

Summary: The loss of iron-bearing minerals to the tailings, especially in the finest fractions (−44 μm), 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.
