| titleOfInvention | METHOD TO EXTRACT LANTHANUM La+3 CATIONS FROM AQUEOUS SOLUTIONS |
| abstract | FIELD: metallurgy. n SUBSTANCE: invention relates to the method for production of pure lanthanum or its oxides from lean or industrial raw materials by method of ion floatation. The method to extract lanthanum La +3 cations from aqueous solutions of salts includes ion floatation using an anion-type surfactant as a collector. Besides, the collector is dodecyl sodium sulfate in a concentration corresponding to the stoichiometric reaction: La +3 +3NaDS=La[DS] 3 +3Na + , where La +3 - lanthanum cation, NaDS - dodecyl sodium sulfate. Moreover, ion floatation is carried out at pH=7.8-8.1, which makes it possible to achieve 98% extraction of lanthanum from aqueous solutions of its salts. n EFFECT: higher extent of lanthanum extraction. n 2 dwg, 1 ex |
