| titleOfInvention | Method for recovering useful elements from rare earth-nickel alloys |
| abstract | (57) [PROBLEMS] To provide a method for recovering a useful element from a rare earth-nickel alloy, which is capable of recovering an effective element safely and economically from the rare earth-nickel alloy. SOLUTION: A rare metal-dissolved metal containing a rare earth metal is added by adding a diluted nitric acid solution prepared by diluting concentrated nitric acid: water at a volume ratio of 1: 1 or more while stirring a rare earth-nickel alloy slurry. Is dissolved at a temperature of 50 ° C. or less to obtain a rare earth-containing nitrate solution, and the rare earth-containing nitrate solution is separated by filtration from the insoluble element compound containing nickel by filtration to obtain a rare earth element-containing nitrate solution and the rare earth-containing nitrate solution. A recovery method of adding a fluorine compound or oxalic acid and / or ammonium oxalate to precipitate and separate the rare earth salt, and further adding ammonium hydrogen carbonate, ammonium carbonate, alkali carbonate or a mixture thereof to the rare earth-containing nitrate solution. A recovery method for recovering a rare earth metal nickel-based master alloy using the precipitate obtained as described above. |
