Recovery of Iron Values from Discarded Iron Ore Slimes
The iron ore slime sample used in this study was procured from a beneficiation plant of a working mine in central India.. The chemical composition shown in Table 1 demonstrates that the sample is rich in iron values along with silica and alumina. The XRD spectrum of slimes shown in Fig. 1a reveals hematite as the major phase along In India, the tailings of iron ore beneficiation are dumped in slime ponds, which is a major environmental concern. In the present study, a new beneficiation circuit was designed to recover the valuable minerals from the tailing effectively.

Feasibility of Producing Pellet Grade Concentrate by Beneficiation
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. Physical processing of low-grade (28% Fe) iron ore slime from Krivoy Rog province of the Ukraine is investigated.
