Advances in Low Grade Iron Ore Beneficiation MECON
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.

07/06/2018 In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required. For these reasons, the rule of thumb is “higher Fe grade, higher price.”. Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use
