Sponge Iron. Sponge iron, also known as direct-reduced iron (DRI), is a type of iron produced by reducing iron ore (typically in the form of pellets or lumps) using a reducing gas or solid reductant, such as coal.This reduction process occurs at a lower temperature compared to traditional iron smelting, resulting in a porous, sponge-like structure, hence the name "sponge iron."
