| titleOfInvention | Process for processing red mud and producing rare-earth metal salts |
| abstract | The invention relates to a process for processing red mud, said process comprising the following steps: (a) providing red mud waste of alumina production (in the following: red mud); (b) further, providing waste containing organic material, and converting to synthesis gas by high temperature pyrolysis; (c) converting the sodium oxide present in the red mud in the form of soluble glass to sodium carbonate with carbonic acid; (d1) magnetizing the Fe 2 O 3 hematite ferric oxide present in the red mud and separating the anti -ferromagnetic Fe 2 O 3 hematite ferric oxide from the remained slurry by magnetic separator; (d2) converting the Fe 2 O 3 hematite ferric oxide present in the red mud to Fe 3 O 4 magnetite ferrous ferric oxide with synthesis gas, and separating the Fe 3 O 4 magnetite ferrous ferric oxide from the remained slurry by magnetic separator; (e) treating the remained slurry obtained in steps (d1) or (d2) with strong acid, thus obtaining metal sulphate solution and SiO 2 and TiO 2 suspension. |
