| Abstract | To realize the effective separation of Na3VO4, Na2CrO4 and the impurity Na2CO3 in a newly developed vanadium production process using concentrated alkaline solution as reaction media, the equilibrium liquid phase solubility and solid phase compositions of the NaOH-Na3VO4-Na2CrO4-Na2CO3-H2O system at (40 and 80) degrees C were measured. The obtained solubility data were afterwards compared with quaternary NaOH-Na3VO4-Na2CrO4-H2O subsystem to investigate the salting-out effect of Na3VO4, Na2CrO4 and Na2CO3. Further, a strategy for effective separation of Na3VO4 and Na2CrO4 from the NaOH Na3VO4-Na2CrO4-Na2CO3-H2O pentabasic system has been proposed on the basis of detailed analysis of crystallization zones.
