This process removes oxygen from the iron ore, leaving a metal with high iron content and low impurities. It is a more efficient process than blast furnace pig iron but still requires substantial processing to make steel. Sponge iron factories have mushroomed in iron ore and coal-rich states like Jharkhand, Odisha, Chhattisgarh, and West Bengal.
