Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process. Aiming towards the good quality (>60% Fe) ore and its non-renewable nature, the mineral rich ore is depleting, and the slimes are increasing at a rate of ∼11–13% for the hematite reserves in India, as reported by the ...

The use of column flotation was considered for the "reverse flotation" of iron ore, where the gangue (quartz) was recovered in the froth product. This use of the froth for carrying the gangue mineral rather than carrying the valuable concentrate significantly changes the operational requirements of the column. The objective of this work was to …
