with red mud of different chemical compositions as well as phase components [4-7], such as high pressure hydro-chemistry method[8], reduction roasting[9-10], direct magnetic separation[11]. As far... to recover alumina and ferric oxide by the process of reduction-sintering, leaching and then magnetic beneficiation. Results of thermodynamic analyses show that ferric oxide should be reduced to Fe......
