True flotation versus entrainment in reverse ionic ...

Summary: The loss of ironbearing 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 highFe hematite. The two main mechanisms for iron mineral loss in the froth in reverse ionic flotation are hydrodynamic dragging and true flotation.
