Summary:In this study, emulsion flow equipment was newly manufactured by modifying the shape of the oil phase nozzle and the filter pore size. An experiment to find the optimal conditions for separating Nd and Dy in the chlorinated rare earth aqueous solution recovered from the dissolution process of the spent Nd magnet was performed with this equipment. The emulsion filling rate was the highest at 100% when the nozzle for spraying oil phase inside the cylinder was type B with a jaw height of 5 mm above the filter and the filter pore size was 40 to 100 μm (P2). Therefore, it was confirmed that these are the most optimal emulsion process conditions in the nozzle when separating Nd and Dy by the emulsion flow method. KCI Citation Count: 0
