Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen from iron ore. The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio

Sponge Iron an overview | ScienceDirect Topics
Unlike the iron sponge process, the SulfaTreat material is non-pyrophoric and has a higher capacity than iron sponge on a volumetric or mass basis. In the process, the inlet gas stream enters the unit through a small inlet separator to separate out any entrained liquid, salt water, and any liquid hydrocarbon in the gas stream.
