Beneficiation
11.5.3.1 Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

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.
