1.. IntroductionDuring the process of iron ore mining in India, large quantities of ultrafines (slimes) are being generated. It has been estimated that around 8 million tons of ultrafines containing a significant value of iron is being discarded as slimes and cannot be used in iron and steel making due to their limitation in size and quality (Narasimhan, 1980).

The separation of iron oxide from banded hematite jasper (BHJ) assaying 47.8% Fe, 25.6% SiO2 and 2.30%Al2O3 using selective magnetic coating was studied. Characterization studies of the low grade ore indicate that besides hematite and goethite, jasper, a microcrystalline form of quartzite, is the major impurity associated with this ore.

A typical Indian iron ore slimes containing 57.2% Fe, 5.81% SiO 2 and 7.05% Al 2 O 3 by wet magnetic separation and selective magnetic coating is investigated and the results revealed that the iron concentrate contains 62.32% Fe with 66.5% iron recovery at medium magnetic intensity of 7.8 kG ( Das et al., 2008 ).

The chemical analysis of the hematite ores on an average conform to 57.8 to 64.5% Fe, 1.56 to 6.5% SiO and 1.3 to 6% Al3O2. These ores subject to beneficiation yield a concentrate containing 61.5 to 66% Fe at 62 to 86% yield. In case of BHQ ore, column flotation technique has been adopted to obtain a concentrate of 66% Fe at 44.7% yield.

12%Magnetic carrier technology has been established in the commercial-scale for wastewater treatment but needs to be translated in iron ore beneficiation by incorporating natural or colloidal magnetite. Similarly, bio-beneficiation processes with gangue reducing bacteria have to be studied at a much larger scale before they see the light of the day.

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

beneficiation of these iron ore tailings may not be completely possible with conventional beneficiation techniques like magnetic separation, gravity separations, floatation etc. because of the presence of large quantity of clay particles and small size of the particles.
