영문 초록

Solvent extraction and separation experiments were carried out using the HCl-PC88A-kerosene extraction system using chlorides mixed with light rare earths (Pr, Nd) and medium rare earths (Tb, Dy). The solvent extraction process parameters were calculated before the experiment using the optimal extraction formula From the experimental results, the optimum purity of the solvent extraction process was confirmed by the optimum extraction ratio theory. The separated high_purity light/medium rare earth elements were precipitated as oxalate_ using oxalic acid_ and then recovered as high-purity light/medium rare earth oxides, by the calcination process.
