1.. IntroductionQuartz is the major gangue mineral present in iron ores. Flotation is the usual concentration method employed for the ores in the fine size range (<149. μm).. Different flotation routes are available: (i) reverse cationic flotation of quartz; (ii) direct anionic flotation of iron oxides; (iii) reverse anionic flotation of activated quartz.

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.
