Indian Iron Ore Scenario : Low Grade Iron Ore Beneficiation

Low Grade Iron Ore Beneficiation In the past 50 years, due to high demand and intensive mining operations, the high grade deposits are depleting fast. By 2019-2020 it is estimated that the relatively low grade reserves are to be tapped. The importance of tailings can be understood by this proverb common to all mineral engineers “Today’s tailing is tomorrow’s ore”. New technologies must ...
