| titleOfInvention | Method and apparatus for separating neodymium and praseodymium |
| abstract | PROBLEM TO BE SOLVED: To separate neodymium (Nd) and praseodymium (Pr) from a solvent, which can be efficiently separated with a small number of extraction stages by a highly productive solvent extraction method and the solvent can be reused. . SOLUTION: An aqueous solution 11 of a complexing agent is used as a scrub solution, Using a quaternary amine solution 12 as an organic phase, a multi-stage mixer-settler device 13 for introducing the two in a reverse direction, A nitric acid-based mixed solution 14 of Nd and Pr is charged into a central portion of a plurality of stages and suspended and allowed to stand. And the solution 12 to extract Nd nitrate and Pr nitrate, d) to the aqueous phase solution 11 side, a step 102 for separating Nd nitrate and Pr nitrate, a step 103 for back-extracting the separated substance with dilute nitric acid, A step 104 of separating Nd with an acidic phosphate solution 15, wherein the excess nitric acid of the solution 11 from which the Nd nitrate is extracted is excessively extracted into the solution 12 from the step 103, and the solution 11 is scrubbed. Regenerating as 105 Separation. |
