Quartz 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.
