What is Sponge Iron? Uses and Benefits Explained

Definition of Sponge Iron. Sponge iron is a form of iron produced by directly reducing iron ore (in the form of lumps, pellets, or fines) to metallic iron by a reducing gas or elemental carbon derived from natural gas or coal. The direct reduction process removes oxygen from the iron ore, resulting in a product that is primarily composed of metallic iron.
