Iron ore is one of the basic raw materials for iron and steel industries. It is predicted that the world steel production may reach more than 2600 million tonnes and in India it may reach 300 million tonnes by 2030 [1]. This has resulted in a large increase in the demand for iron ore. It is a great concern for steel industries to either receive
