ABSTRACT
Effective separation of NH4VO3 from NH4HCO3 or (NH4)2CO3 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)2CO3 NH4VO3 H2O systems at (40 and 70) deg C were studied, respectively; thus, a strategy for effective separation of NH4VO3 from NH4HCO3 or (NH4)2CO3 solution has been proposed.
