Collecting Agent–Mineral Interactions in the Reverse Flotation of Iron
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. This review is focused on the reverse flotation …

Physiochemical separation of iron ore
The floatability of iron ores can differ widely due to the composition of the iron minerals and the nature and association of gangue minerals. The main objective of iron ore flotation is to upgrade the ore and produce a concentrate by removing quartz, aluminum silicate minerals (e.g., kaolinite), and aluminum oxide minerals (e.g., gibbsite). …
