| Abstract: | The process of vanadium extraction from acid leaching solution is discussed.The process is suitable for a kind of stone coal mineral in the west of Henan province.Several programs are contrasted by experiments and the process that neutralization-deoxidization-P204 extraction-stripping with sulfuric acid-oxidization-V2O5 deposition is proved the best route.In the process,extraction system is 15%P204 10%TBP 75%coal oil and 1.5 mol/L sulfuric acid solution is stripping agent,the quality of production obtained by this process can reach GB3283-87 metallurgy 99 standard and the recovery rate of vanadium is 93.2%. |
