The present practice of beneficiation of iron ores in India produces lumpy ores (for blast furnace), classifier fines (for sinter plant) and slimes (Below 150 mm) which are stored in tailings pond. the estimated generation of slimes is 10-25% of the iron ore mined amounting to 18 million tonnes per year. Besides the loss of iron ore mined amounting …

Gravity separation and magnetic separation are mainly used to separate coarse-grained and medium-grained weak magnetic iron ore (20~2 mm). During gravity separation, the gravity separation of coarse-grained and very coarse-grained (>20 mm) ores is usually carried out with heavy media or jigging; reselection method.

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. …

Some challenges associated with gravity separation of the Bayan Obo ore are that gangue minerals (e.g. barite) have similar specific gravities to the desired rare earth minerals and report to the concentrate stream. In addition, gravity separation is ineffective at separating very fine particles resulting in large losses of rare earths (Ming ...
