Bio-mining of Lanthanides from Red Mud by Green Microalgae [PDF]

Molecules, 2019
Red mud is a by-product of alumina production containing lanthanides. Growth of green microalgae on red mud and the intracellular accumulation of lanthanides was tested. The best growing species was Desmodesmus quadricauda (2.71 cell number doublings/day)

Reduction behavior of iron in the red mud

Journal of Mining and Metallurgy, Section B: Metallurgy, 2021
Red mud or bauxite residue contains significant quantities of industrial metals such as Fe, Al, and Ti, as well as rare earth elements such as Sc, Ce, and La. The authors performed a laboratory-scale project dealing with stepwise recovery of valuable elements from two bauxite residues, namely Iranian red mud (IRM) and Turkish red mud (TRM).
