Abstract — A bauxite ore can be utilized in Bayer Process, if the mass ratio of Al 2 O 3 to SiO 2 is greater than 10. Otherwise, its Fe x O y and SiO 2 content should be removed. On the other hand, removal of TiO 2 from the bauxite ore would be beneficial because of both lowering the red mud residue and obtaining a valuable raw material containing TiO 2 mineral. …
