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.

Utilization of Pellet Fines in the Iron Ore Sintering Process
The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering process. 5 …
