Iron ore beneficiation key for India's steelmaking goal
Iron ore beneficiation has lagged in India because of challenges such as the area required for tailings and transportation costs, state-controlled mining firm NMDC technical director Vinay Kumar said. Tailings refer to the waste generated by the beneficiation process. Constructing more slurry pipelines would reduce logistics expenses, Kumar added.

Advances in Low Grade Iron Ore Beneficiation
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.
