To tackle the challenge of bauxite residue (BR), generated during alumina production, as well to recover some its metal content, three combinatory H2-based processes were utilized. Firstly, Greek BR was mixed with NaOH produce water soluble Na-aluminates and roasted under pure H2 gas in order reduce Fe+3 content. Then first process combined leaching magnetic separation, second melting last included wet separation. The media resulted dissolution Na-aluminate phases production Al, Na-ion rich...
