We have hands-on experience with all types of ore bodies and mineralogy. Our work covers the entire iron-ore value chain, from mining through to crushing, grinding, and beneficiation by gravity, magnetic, or heavy media separation. Next comes flotation and filtering, followed by downstream processing, such as pelletizing and sintering.

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.
