During the production of hot briquetted iron (HBI) from raw iron oxide pellets in the Midrex process, a wide variety of residues are generated. These residues are sludges, screened fines, and dust and are generally rich in iron oxides. [1, 2] Hence, they have the potential of being recycled back to the Midrex shaft after having been agglomerated.
