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.
Iron Ore Beneficiation Process. During the last ten years great strides have been made on the Mesabi range in the practice of beneficiating low grade iron ore material By beneficiation is meant all methods of removing impurities and raising the iron content to a point where it can be sold in open market the principal impurities being silica and moisture
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. It has been observed that beneficiation of low grade ores invariably pose specific challenge due to the presence of clayey/earthy ...
Barsua iron ore mine in India has adopted Remco Jigs for beneficiation of low-grade iron ore fines. Bateman's Apic jig is being used in iron ore mines of South Africa and has demonstrated how the technology is suitable for the separation of fine ferrous ores. A Batac jig is installed to reduce alumina content of iron ore fines from Noamundi

As high-grade iron ore deposits are gradually being depleted, more difficult-to-process ores such as goethite-rich, low-grade iron ores and tailings are now being processed. These ores often contain impurities and require some form of beneficiation in order to achieve the typical grades required for sale to downstream steel producers.
range. The residual are low grade, unclassified resources of lumps and fines or high, medium, low or unclassified grades of lumps and fines mixed. The cut-off grade for estimating the hematite resources has been taken as 57% Fe. If the cut-off grade is reduced to say 43% Fe, the iron ore resources will increase considerably and thus
