Abstract: The separation methods of vanadium and chromium from solution containing vanadium and chromium,including solvent extraction,chemical precipitation,ion exchange,crystallization and electro-chemical methods were introduced.The technical principles and process flows of the 5 methods mentioned above were described,and the advantages and disadvantages of them were analyzed and summarized.The solution containing low concentration of vanadium and high content of chromium was obtained by sodium roasting and water leaching using the high chromium vanadium slag from Hongge mining area as raw ma-terial,and the high contents of impurities in the solution led to the difficulty in separation of vanadiumand chromium.By comprehensive comparison,a conclusion is drawn that the chemical precipitation method is suitable for the separation of vanadium and chromium in the solution with low concentration of vanadium and high content of chromium,which has the advantages of simple process,low cost,easy op-eration and industrialization.Owing to the high purity of products,crystallization method has a good ap-plication prospect in the field of separation of vanadium and chromium.
