실험 절차

Adding 9 m3 of magnesium bicarbonate solution (MgO: 15 g/L, Fe: 1.1 ppm, Al: 0.5 ppm, saturated with CO2) into a reactor containing 10 m3 of neodymium acetate solution (0.2 mol/L) to react for 2 hours at 25° C., and controlling the pH value of mother liquor at 5.5, neodymium ions are precipitated and neodymium carbonate is obtained. Subsequently, the neodymium carbonate is filtered, washed, dried and finally calcined at 700° C. for 2 hours to produce neodymium oxide.
