Brief Description

Description :

The process utilises ~100% waste materials to yield a value added product. This invention is useful for converting steel plant wastes fines / mining waste fines such as iron ore slime/fines, middling and rejected coal containing more than 25 % ash into a highly metallised (Metallisation > 96%) low Sulphur (0.006%S) DRI suitable for induction furnace, electric arc furnace and blast furnace for iron and steel making.
