Direct Reduced Iron (DRI), also known as Sponge Iron, is a high-quality metallic iron produced by the direct reduction of iron ore using natural gas or non-coking coal. It is widely used as a clean and efficient raw material in steel-making processes such as Electric Arc Furnaces (EAF) and Induction Furnaces (IF).
