Bioleaching of vanadium by Acidithiobacillus ferrooxidans
Clinker has greater leachability than vanadium-titanium magnetite and steel slag. • Factors influencing this bioleaching process have been systemically studied. • XRF and EDS results confirm the reduction of vanadium in the solid mineral. • Vanadium in acid-soluble and oxidizable phase is more easily leachable.
