Smelting of Bauxite Residue (Red Mud) in View of Iron .

2015/10/07· During acid leaching of bauxite residue (red mud), the increase in dissolution of rare-earth elements (REEs) is associated with an increase in iron dissolution, which poses problems in the downstream processing. Therefore, it would be beneficial to remove iron from bauxite residue by smelting reduction. The slag generated in the smelting reduction process could then be further process.processing of bauxite oresBAYER PROCESS Bayer process is the process of refining alumina. from bauxite (aluminum ore containing 3050% of hydrated aluminum oxide) by selective extraction of pure aluminum oxide dissolved in sodium hydroxide.
