Iron Ore Beneficiation Introduction. Iron Ore Beneficiation increases the grade of iron whilst maximising recovery and reduces the content of ultrafine low grade slimes to maximise return on investment from the mining process prior to sale or further refining in the iron making process.
The R&D efforts undertaken at NML-Madras Centre, India in this direction have been highlighted. Beneficiation of iron ores in general and column flotation in particular are highlighted in this paper. This would also mitigate the environmental problem created by the dumping of huge quantities of low and medium grade iron orefines.
The results obtain indicate that it is possible to beneficiate low grade hematitic iron ore from a feed of 50.74% Fe to 65.11% Fe with an acceptable recovery of 71.88%.
The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants). In the process, low grade iron ores are dry-ground, preferably to their liberation size & passed through a fluidized bed roaster.
Thus, beneficiating the low-grade iron ores to remove the gangue minerals and enhancing their grade is an attractive proposition today. Among the known iron deposits in Karnataka, many are of low-grade which require beneficiation to produce an acceptable feed for steel making plants.

Beneficiation: Beneficiation is the process which improves the economic value of the ore by removing gangue minerals. The Committee noted that there has been a continuous depletion of high-grade iron ore in India. Hence, it is necessary to beneficiate low-grade iron ore into commercial-grade to fulfil the demand for raw material for steel making.
