Solubility Data in the Ternary NH4HCO3-NH4VO3-H2O and (NH4)(2)CO3-NH4VO3-H2O Systems at (40 and 70) degrees C

Effective separation of NH4VO3 from NH4HCO3 or (NH4)(2)CO3 solution is an important step in the newly proposed vanadium production process based on sodium salt roasting. The solubility data for NH4HCO3-NH4VO3-H2O and (NH4)(2)CO3-NH4VO3-H2O systems at (40 and 70) degrees C were studied, respectively; thus, a strategy for effective separation of NH4VO3 from NH4HCO3 or (NH4)(2)CO3 solution has been proposed.
