Studies were carried out on the removal of alumina from iron ore slime containing (%) Fe2O3 75.7, Al2O3 9.95, SiO2 6.1, Fe (total) 52.94 with the help of Bacillus circulans and Aspergillus niger ...

This beneficiation technology is not suitable to Indian iron ore slime due to its typical mineralogical composition. Compositionally, Indian iron ore slime contains goethite as major iron bearing mineral and kaolinite as major gangue bearing mineral. Earlier efforts were made to recover iron values from iron ore slime [5], [6], [7], [8].

The beneficiation and enrichment tests on Bolani iron ore slime showed the possibility of upgrading the slime from 53.71% Fe, 5.25% SiO, and 6.25% A1203 to 63.5% Fe, 1.8 …

A typical high-alumina containing iron ore slime from the eastern Indian sector containing 58.13% Fe, 6.48% SiO2, 4.9 % Al2O3 and 5.35% LOI, have been evaluated to find out whether grinding of the ...

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 …

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 …

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 …

We present our successful results on the natural iron ore slime sample obtained from one of the mines in India. We have been able to achieve a concentrate assaying >67% Fe, and <3% Al 2 O 3 and 2. ...

Beneficiation of alumina rich iron ore slimes is a major challenge for the Indian iron ore industry. High alumina is deleterious for the performance of both blast furnace as well as sintering plants. Slimes generally contain 5 – 10% alumina, and hence despite assaying as high as 60% Fe, those are dumped in tailing ponds.

A typical high-alumina containing iron ore slime from the eastern Indian sector containing 58.13% Fe, 6.48% SiO2, 4.9 % Al2O3 and 5.35% LOI, have been evaluated to find out whether grinding of the ...

The beneficiation potential of the iron ore slimes produced from the washing plants and tailing ponds of Kiriburu mines assaying up to 60% Fe, 3.34% SiO2, and 2.93% Al2O3 is analyzed.

iron ore slime. 2. Experimental Iron ore slime collected for this study was screened by wet sieving technique into three broad size classes such as coarser than 50 μm, between 50 to 25 μm and finer than 25μm. This classification is based on the prevailing under-standing that existing beneficiation methods are suitable for

Synopsis. Researchers at IIT Madras and Kanpur devise a novel method to repurpose discarded iron ore waste, termed "slime," into reusable material via a microwave-based beneficiation process.

The beneficiation of iron ore fines and slimes has not only received attention in India but also in many iron-producing countries in the world due to the fast depletion of the high-grade ores. ...
