Beneficiation is followed by processing activities such as smelting and refining. The beneficiation process begins with milling, which is followed by flotation for further beneficiation. At the first stage, extracted ores undergo the milling operation to produce uniformly sized particles for crushing, grinding, wet or dry concentration.

However, some studies have focused on beneficiation of Indian iron ore fines and slimes using wet high intensity magnetic sep-arator, spirals, flotation, and selective flocculation [ 3, 7, 12, 14, 15,21]. Till date, there is no specific study with detailed charac-terization for beneficiation of Indian iron ore fines having ultra-fine liberation ...

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.
