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 ...
Froth flotation process is one of the best separation techniques to upgrade and recover the valuable minerals from ores [1,2,3].Its effectiveness is dependent on the differences in surface wettability displayed by solids (mineral particles) at the air-water-solid interfaces [4, 5].In this approach, hydrophobic particles attach to air bubbles, buoyantly …
Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include.
Therefore, this work is aimed to experimentally study the iron ore slime beneficiation using a novel 100 mm hydrocyclone (with small cone angle, tapered vortex finder and optimum cylindrical length) design developed by computation fluid dynamics (CFD) simulation studies. ...
