We have been developing a new process for the separation and recovery of rare earth metals using molten salt electrolysis and an alloy diaphragm.
This new process was first applied to chloride melts, and the separation of Dy from Nd and Pr were investigated using Cu, Ni and Zn cathodic electrodes in molten LiCl-KCl-DyCl3-NdCl3 and LiCl-KCl-DyCl3-NdCl3-PrCl3 systems. The highest mass ratio of Dy/Nd+Pr in Dy-Nd-Pr-Ni alloy sample was found to be 50 at 0.65 V (vs. Li+/Li) for 1 h by ICP-AES. In this study, the investigation of Dy permeation through Dy alloy diaphragm using molten salt electrolysis was investigated. The Dy permeation experiment was conducted with electrolytic cells in molten LiCl-KCl systems at 723 K in order to confirm the theoretical feasibility of the present process.
