Beneficiation of iron ore slime using Aspergillus niger ...

01/10/2006  Iron ore slimes containing around 48–62% Fe are generated from the iron ore washing plants and are disposed into tailing ponds without any further utility. The slimes are not suitable in iron and steel making due to the extremely finer size and presence of higher amount of gangue constituents. Several beneficiation techniques have been tried from time to time to reduce the gangue ...

01/05/1992  The iron ore slimes (d80 ∼ 50 µm) generated at Noamundi iron ore washing plant (TISCO), assaying 57% Fe, 4% SiO2 and 8.3% Al2O3, have been subjected to hydrocyclone studies. The effects of different design and operating parameters have been studied to get a product suitable for subsequent use in the sinter mix. The studies indicate that it is possible to obtain a product containing

Beneficiation of Iron Ore Slimes using Optimized ...

Beneficiation is the process of separating iron ore from the gangue particles like alumina, silica. Increasing the iron ore demand, with the faster depletion of high grade iron ore, it is the time to use low grade iron ore slime as a feed stock rather leaves as a waste. Mainly coarser fraction is rich in iron content and finer fraction contained large amount of gangue.
