Sponge Iron - an overview ScienceDirect Topics

Composite pellets or briquettes are formed from intimate mixtures of finely ground iron oxide (iron ore) and carbon (coal or charcoal). When heated to 1250–1400 °C, the iron oxides are reduced to form metallic sponge iron, and the other mineral components form a slag phase. Fast reduction kinetics is achievable because of the close proximity of the carbon and iron oxide particles.

What is Sponge Iron? (with pictures) - InfoBloom

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
