| 简介 | The present invention relates to a method for recovery of rare earth metals (REM) from diluted aqueous acidic solutions comprising steps of liquid-phase extraction of REM into an organic phase and re-extraction of REM from the organic phase. The re-extraction is carried out by precipitation of REM as a solid phase in the form of a poorly soluble salt of a strong acid (pKa<0). Recovery of REM into the concentrate is up to 99% in the course of one stage of the re-extraction. | ||
