| Abstract: |
| Stone coal widely distribute and reserve in china, the vanadium in it has highly industrial value . Summarize and analyzes the main kinds of direct acid leaching vanadium and the application of oxidant and leaching aid used in leaching process, the results shows, add leaching aid and oxidant into the direct acid leaching process can effectively reduce the amount of acid、shorten leaching time and keep highly leaching rate. Studying on new efficient oxidant and leaching aid is the important direction of direct acid leaching vanadium from stone coal. |
