KU Leuven recently published a landmark review paper on red mud valorisation in the Journal of Sustainable Metallurgy. It offers solutions to the long-term storage of bauxite residue (red mud) which is so harmful to our global environment. Although there is no immediate large scale utilization of bauxite residue, some bauxite residues contain considerable concentrations of rare-earth elements (REEs) and the recovery of these REEs together with or without other metals and utilization of the generated residue in other applications (e.g., building materials) can solve the storage problem of bauxite residue. This paper reviews the recovery of REEs, possibly alongside other valuable metals, from bauxite residue. Read more about the great work being done at KU Leuven.
