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%

[PDF] Mineralogy and Geochemistry of a low grade iron ore ...

The gradual depletion of high-grade iron ores has necessitated the exploitation of low/off grade iron ore reserves of India. The role of geochemical and mineralogical characterization is paramount to arrive at the process flow sheet development for such complex ores. Detailed studies were conducted on iron ores of Bellary-Hospet sector using microscope, XRD, TG, and EPMA techniques.
