Separation of Dy and Nd by DGA extractant using batchwise multi-stage extraction

Sasaki, Yuji  ; Matsumiya, Masahiko*

In our laboratory, the mutual separation of lanthanides by batch-wise multi-stage extraction is conducted. Dy is introduced into Nd-magnet, for this recycle mutual separation of Dy and Nd in important. Here, the solvent extraction method is used for their separation. We confirm the consistency between calculation and experimental results and perform the separation experiments of Dy from Nd. The results will be shown in the presentation.
