Outline of Final Research Achievements

In this study, we developed a novel extraction-electrodeposition process using ionic liquids for the purpose of efficient recovery of rare earths. At first, the extraction behaviors of rare earths (Nd, Dy) were analyzed by slope analysis. In addition, the solvation structures of the extracted rare earth complexes were investigated from Raman spectroscopy. As a result, the extracted species were [RE(TBP)3(TFSA)3], (RE=Nd, Dy). Furthermore, a series of extraction-electrodeposition process was performed for the actual Nd-Fe-B spent magnets. Nd and Dy were efficiently extracted from TBP/[P2225][TFSA] media and each metal was obtained by the potetiostatic electrodeposition using ionic liquids including [RE(TBP)3(TFSA)3] species. Then, the cathodic current efficiency was increased with increasing the extracted rare earth complexes. This result allowed us to conclude that the extraction-electrodeposition process will be hopeful to apply for the Nd-Fe-B spent magnets for near future.
