What is Sponge Iron? (with pictures) - Info Bloom

04/02/2021  Sponge iron is created from iron ore. Sometimes known as direct-reduced iron, sponge iron is a product that is produced using iron ore. The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source.
