Abstract: Stone coal vanadium ore is our peculiar vanadium resources with abundant reserves. In recent years, the manufacture and research of the technology on vanadium extraction from stone coal are developing rapidly. Discussed the main technology of vanadium extraction from stone coal,bases on this point, analyzed the key problems which affected the technology of vanadium extraction from stone coal with comparing the advantages and disadvantages of each technology and industrial applicability, then analyzed the recovery influence by roasting and leaching stage. Summarized the research direction of vanadium extraction from stone coal.

Key words: Stone coal, Roasting, Leaching, Direct acid leaching, Recovery
