    • Abstract
  • Extraction separation vanadium and molybdenum from stone coal acidic leach solution using P204was studied. Some parameters of extraction and stripping, such as pH of solution, the species of strippingagent, the concentration of stripping agent and the volume ratio of organic phase to aqueous phase wereoptimized by a series o f tests. The results showed that after deacidizing the stone coal acidic leach solutionwith Na2S2O3, the extraction of vanadium and molybdenum can reach 84.1 % and 81.1 %, respectively. Thestripping of vanadium can reach above 99 % using 1.5 mol/L H2SO4 as the stripping agent and molybdenumcannot be stripped under this condition. When 60 g/L NH4HCO3 solution was used as the strippingagent, molybdenum can be stripped effectively and the stripping can reach 76.4 %. Vanadium andmolybdenum can be separated by using different stripping agent in the process of stripping.
