Abstract 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. …

the close association of the REE with iron and gangue minerals. A great deal of work had been done in China on the beneficiation of the Bayan Obo REE deposits since the 1950s, and more than 20 beneficiation techniques have been reported. Significant progress on the processing of REE minerals was made in the early 1990s (Yu, 2000).
