Recovery of Iron Aluminum from Bauxite Residue

“Recovery of Iron Aluminum from Bauxite Residue by Carbothermic Reduction and Slag Leaching” by Ekstroem, K. E., Bugten, A. Voll, van der Eijk, C., Lazou, A., Balomenos, E., Tranell, G. investigates the recovery of major components from bauxite residue through carbothermic reduction and subsequent slag leaching. Iron is primarily recovered as pig-iron, and the addition of lime helps create highly leachable mayenite phase in calcium aluminate slags.
