Iron Ore Tailing Beneficiation
Iron ore tailing/slime (-150 μm) is produced after scrubbing and wet screening of a low-grade iron ore. Tailing beneficiation of iron ore has been addressed either by flotation or wet high intensity high gradient separation. The present study aims to recover iron values from discarded slime containing assay ~56% Fe, ~6.5% SiO 2, and ~7.0% Al 2 O 3
