| titleOfInvention | Method for Extracting and Separating Light Rare Earth Element |
| abstract | The target light rare earth element is obtained by contacting an organic phase containing an extractant with an aqueous solution while adding an alkali solution thereto in a countercurrent multi-stage mixer-settler and bringing the organic phase into contact with an aqueous acid solution to back- Are extracted and separated from an aqueous solution containing the elements. The extractant is a dialkyldiglycol amic acid having the general formula: R 1 R 2 NCOCH 2 OCH 2 COOH, wherein R 1 and R 2 are alkyl and at least one has at least 6 carbon atoms. |
