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.

Following a series of beneficiation tests, it could be shown that the iron content in the final concentrate of the Egyptian iron ore would be significantly below 58%, which meant that the ore could only be sintered or pelletized for …

The Tilden mine operation, Cleveland Cliffs Company employed cationic flotation as part of their iron ore beneficiation process [7]. Many researchers [ [61], [62], [63] ] have proposed that silica and alumina content could be reduced by reverse cationic flotation as a value augmentation step on a pre-concentrated sample.

Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, …

Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting. Fine-grained hematite refers to iron ore with an embedded particle size of less than 0.02mm. Based on the genesis of ...
