J. Cent. South Univ. (2018) 25: 2349-2359 DOI: https://doi.org/10.1007/s11771-018-3919-0 Safe utilization of chromium-bearing vanadate residue by recovery of vanadium and chromium based on calcium... solution. Results indicate that the stability of calcium vanadate and calcium chromate depends on pH and [HCO3-]. CaV2O6·4H2O transforms into CaV2O6·4H2O, CaV2O6·2H2O, CaV2O6, Ca2V2O7·2H2O, and Ca5(VO4)3(OH......
