. Because of the low grade of vanadium in the processed ores and the depletion of concentrated ore deposits in the world, many industrial sub-products, including the converter and smelter slag[3-5.... The common grade of vanadium in this ore is usually less than 2%. Black shale is the most important resource for vanadium extraction in China, which accounts for more than 87% of the domestic reserve......
]. Clay vanadium mineral, like vanadium-titanium magnetite and vanadium-bearing stone coal, is an important resource for vanadium [2]. The extraction of vanadium from clay ore usually adopts roasting...-leaching on account of its catalysis oxidation for the dissolution of valuable metals [8, 9]. Studies have been conducted in the applications of A. ferrooxidans in vanadium ore. HUANG et al [10......
