Here, this study highlights the potential of red mud/bauxite residue, an industrial waste product generated during alumina extraction as a flux for iron and steelmaking. The thermodynamic feasibility of using red mud as a flux in the presence of different reducing agents is evaluated. Potential approaches to decarbonize iron and steel production while utilizing red mud as a flux, as well as the benefits of red mud remnant after iron extraction, are discussed.
