The generation of iron ore slimes in India is estimated to be 10-25 by weight of the total iron ore mined the iron ore values are lost to the tune of 15-20 million tones every year. In addition, these slimes stored in massive water ponds poses enormous environmental hazard.
Fine particle processing of iron ore slimes from Orissa, India ... beneficiation process for recovering the iron values from ... four different iron ore slimes samples followed by the effect of desliming and other machine parameters of VPHGMS for one sample. The effect of scavenging, cleaner stage
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 Al 2 O 3, and 10.19 SiO 2.Kaolinite and quartz was found to be the main gangue minerals and they formed porous and friable oxide and hydroxide of iron.
Detailed characterization followed by beneficiation of low-grade iron ore slime from Jilling Langalota deposit, India, was studied. The work involved separating the gangue minerals viz. quartz and kaolinite to form iron-bearing minerals, mostly hematite and goethite, as identified using XRD analysis to produce a suitable concentrate for downstream processing.
In India, Bellary-Hospet region is endowed with large reserves of good quality of iron ore. The iron ore of this region is although rich in iron content but suffers from two disadvantages. One is high alumina content in the iron ore and second is softness of the ore which generates huge quantity of fines and slimes during mining and beneficiation.
The experimental results show that it is possible to raise the iron content up to 64.17 at a yield of 37.3 with a simultaneous decrease in the alumina content, down to 1.17.Earlier work indicates that beneficiation of iron ore slime containing very low iron and high alumina and silica is quite difficult.
After beneficiation iron ore availability can improve by about 50. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative 1. Utilisation of low grade iron ores after beneficiation. 2. Reduction in slime loss by recovery of iron values from slimes. 3.

Jan 02, 2012 Beneficiation of high alumina iron ore fines from Noamundi, India is studied for producing sinter pellet grade concentrate. The iron ore fine sample has a feed grade of 59.77Fe, 4.71SiO 2 , and 5.89Al 2 O 3 with 5.53 of LOI Loss on Ignition. From the characterisation studies, it is revealed that the sample contains huge quantity of goethite which is partially weathered,
reserves of good quality of iron ore. The iron ore of this region is although rich in iron content but suffers from two disadvantages. One is high alumina content in the iron ore and second is softness of the ore which generates huge quantity of fines and slimes during mining and beneficiation. JSW Steel limited operates 3.0 mtpa and
The iron ore deposits in India are rich in iron content but usually contains high alumina and silica. The current industrial practice results three products namely lump, fines and slimes. The lump and fines with or without beneficiation are directly fed to the blast furnace and sintering plant respectively while the super fines or slimes are presently discarded as tailings.

BENEFICIATION OF INDIAN IRON ORE SLIME AND FINES EFFECT OF SURFACE-ACTIVE AGENT AND SPECIFIC ION EFFECTS JYOTIRMOY SARMA, SANCHAYITA RAJKHOWA, NAMRATA SARMA AND SEKH MAHIUDDIN The suspension stability in 10 slurry of iron ore fines and slime was studied by using three surface-active agents at pH 8.
The iron ore processing plant at Bolani mines of Steel Authority of India Ltd., India generates about 20-25 of ROM as slimes during wet operation. These slimes are very fine in nature - 0.5mm and its average iron content ranges between 52-55. This material is presently being discarded as process waste due to its inferior grade.
Wide reserves of iron ore is found in India. Due to the high quality of iron ore available in India, large deposits of Banded Haematite Jasper BHJ are left unused because of the presence of silica in unwanted quantity. ROM is put through washing to remove the clayey matter due to the presence of alumina and silica in iron ore leading to slime generation which are disposed of in tailing ponds. Slime in
