Flotation of Iron Ore: A Brief Review MDPI

2020-7-30 · Abstract: Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation.

Investigation of the reverse flotation of iron ore in

2020-5-1 · Fine hematite particle loss decreases significantly with decreasing solids concentration, due to significantly reduced water recoveries and associated entrainment. This suggests that the flotation of iron ore may be improved by operating at lower solids concentrations. However, this would need to be tested at an industrial-scale. •
