How do you produce sponge iron powder?

Sponge iron powder is produced through the direct reduction of iron ore, typically using natural gas or coal as a reducing agent. The iron ore, often in the form of pellets or lumps, is heated in a reduction furnace at temperatures around 800-1,200°C, where it undergoes a chemical reaction that removes oxygen, resulting in sponge iron. This spongy material is then further processed and milled to produce fine iron powder. The final product is characterized by its high purity and low impurities, making it suitable for various applications in Metallurgy and powder metallurgy.
