How to Manufacture Pig Iron: How Pig Iron is made?

2021-5-27  (3) Sponge Iron Process: As the name implies, the spongy iron is obtained by the reduction of lumpy iron ore or iron ore pellets from the oxide form into the metallic state. The iron content of the product so obtained varies from 90% to 94% and the balance represents the traces of gangue and residual iron oxide.
