Procedure
Adding 6.7 m3 of the above magnesium bicarbonate solution into a reactor containing 6 m3 of neodymium citrate solution (0.27 mol/L) to react for half an hour at 35° C., and controlling the pH value of mother liquor at 5.7, RE ions are precipitated. And then neodymium carbonate is obtained after 12-hours-aging, filtration, washing and drying.
Workup
- customto react for half an hour at 35° C.
- customare precipitated
