iron ore resources have become a national priority. As per the recent national steel policy, our country will be producing about 110 million tons of steel per annum by 2020 requiring around 42 million tons of iron ore. The iron ore exports are projected to a level of 114 million tones and it amounts to total production of 300 million tons by 2020.

Abstract Beneficiation of lowgrade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, lowgrade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity separators. Hence, alternative beneficiation ...
