Beneficiation of low grade iron ore slime from Chitradurga, India was studied with a view to produce pellet grade fines. The slime sample had a feed grade of 49.86% total Fe, 7.93% Al2O3, and 10.19% SiO2. Kaolinite and quartz was found to be the main gangue minerals and they formed porous and friable oxide and hydroxide of iron. Over 54%

Subrata Roy used multi gravity separator for improving the recovery of fine iron ore particles [15]. MGS was used to reject graphite from lead concentrate by Yerriswamy et al. [16]. There are no evidences of usage of MGS for beneficiation/ separation of iron values from sub grade iron ore in the literature.

Mineralogical Characteristics of Iron Ores in Joda and ...

Precambrian iron ores of the Singhbhum-North Orissa region occur in eastern India as part of the Iron Ore Group (IOG) within the broad horse-shoe shaped synclinorium. More than 50% of Indian iron ore reserves occur in this region. Massive-hard, flaky-friable, blue dust and lateritic varieties of iron ores are the major ore types, associated with banded hematite, jasper and shales.
