Abstract 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 conclu-
ded as follows ① acid leaching would be preferred during the process of ore position 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.
