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.
