Sponge Iron
Sponge iron adopts direct reduction ironmaking method to obtain iron with sponge-like pores inside. Sponge iron is produced by low-temperature reduction of iron ore in a rotary furnace, shaft furnace, or reactor. Since the reduction temperature is lower than the melting temperature of the ore, the iron ore still maintains the shape of the ore ...

What is Sponge Iron?
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.
