반응 단계
Adding 6 m3 of neodymium chloride solution (1.5 mol/L) into a reactor containing 27.5 m3 of the above magnesium bicarbonate solution to react for 3 hour at 35° C., and controlling the pH value of mother liquor at 8.0, neodymium ions are precipitated, and then neodymium carbonate is obtained after filtration, washing and drying. At last, neodymium oxide is obtained from calcination of neodymium carbonate at 650° C. for 2 hours.
