Iron ore is the basic raw material for iron and steel making. India is among the leading producers of iron ore in the world and produces about 150 million tons per annum (U. S. []).The total reserves of iron ore in India is around 28.5 billion tons, of this hematite ore is considered to be the most important iron ore because of its high grade quality and lumpy nature.

grade iron ore pellets. Presently, <10% of global merchant iron ore exports are DR-grade pellets or pellet feed/concentrate (see Fig. 1). The use of low-er-quality raw materials, such as BF-grade pellets or lump ore, in the DRI-EAF process causes issues downstream in the EAF such as higher slag vol-ume, higher energy consumption and yield losses.
