State-of-art Development of Vanadium Extraction from Stone Coal

The distribution of stone coal in China was introduced and processes of vanadium extraction from stone coal,including their advantages and disadvantages,were reviewed.A survey of its history and current status suggests that the development trend of vanadium extraction from stone coal could be concluded as follows: ① acid leaching would be preferred during the process of ore decomposition;② various methods could be used to separate and concentrate vanadium from the acid leaching solution;③ various products containing vanadium could be obtained;④ various valuable elements could be recovered in the process.
