A novel complex acid leaching route for extracting V is proposed. The selectivity of the H3PO4–H2SO4 system is superior to H2SO4. Fe3+ coordinated with PO43− to reduce Fe impurity; H3PO4–H2SO4 leaching separated the V and Fe.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
