Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Adding 6 m3 of scandium chloride solution (0.5 mol/L) into a reactor containing 18.3 m3 of the above calcium bicarbonate solution to react for 3 hours at 35° C., and controlling the pH value of mother liquor at 8.0, scandium ions are precipitated. And then scandium carbonate is obtained after filtration, washing and drying. to react for 3 hours at 35° C. are precipitated
