Characterization and Beneficiation of Iron Ore Tailings by ...

2015-10-20  In the present paper, an attempt has been made to beneficiate iron ore tailings by selective flocculation using guar gum and starch as flocculants along with sodium hexametaphosphate (SHMP) as the dispersant. The mineralogical studies carried out initially indicated the presence of hematite and goethite as major iron bearing mineral phases along with quartz and kaolinite as major gangue ...

Re-beneficiation of iron ore tailings from the ...

Re-beneficiation of iron ore tailings from the conventional beneficiation plants The hematite ore (Fe 2 O 3) is always associated with limonite goethite ores, which cannot be attracted by high gauss magnetic separators in the conventional beneficiation plants. Such tailings have 30-50% left-over Fe, which is a waste of natural resources.
