| Abstract: | A precipitation method is proposed for separation of the rare earth neodymium and barium from the used rare earth superconduct material. First barium is precipitated from material by adding sulphuric acid to solution to form BaSO_4. The rate of recovery of Ba is 92.67 %. The sulphuric double salt precipitate is adopted for rare earth neodymium separation. That the acidity of solution, the temperature and the amount of precipitating agent affect the formation of the double salt is studied. The purity of neodymium separation product is tested by X ray diffraction. |
