Extraction of V2O5 from stone coal containing Vanadium from Westnorth China is investigated. The results show that Vanadium of about 80% can be leached with sulfuric acid under the condations that temperature is 85℃, mass ratio of liquid and solid is 1∶1, ore size is -60 mesh. Then puritic solution containing V2O5 can be acquired after being extracted with P204 and TBP dissolved in sulfonated kerosene and stripped with sulfuric acid. Refine V2O5 (purity is 98%) can acquired by precipitating with ammonium water and pyrolysis.
