Method for extracting and separating light rare earth element |
| abstract |
A target light rare earth element is separated from an 5 aqueous solution containing two or more of La, Ce, Pr and Nd by contacting an organic phase containing an extractant with the aqueous solution in a counter-current flow multistage mixer-settler while adding an alkaline solution thereto, and contacting the organic phase with an acid aqueous solution 10 for back-extracting the target element. The extractant is a dialkyl diglycol amic acid having formula: R'R 2NCOCH 20CH2 COOH wherein R' and R 2 are alkyl, at least one having at least 6 carbon atoms. |
