Re-beneficiation of iron ore tailings from the

Once the iron ore becomes magnetite, it is much easier to beneficiate & pelletise it. The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants).

Beneficiation of Synthetic Iron Ore Kaolinite Mixture

2013-12-24  The Indian iron ore tailings typically contain hematite, goethite and clay materials. The beneficiation of these iron ore tailings will not only improve the overall recovery of the process but also will reduce the amount of materials to be disposed of as gangue materials. The effective beneficiation of these iron ore tailings may not be completely possible with conventional beneficiation techniques like magnetic separation, gravity separations, floatation etc. because of the presence of large quantity of clay particles and small size of the particles. Non the less these can be beneficiated
