METHOD FOR EXTRACTION OF VANADIUM Russian patent published in 1998 - IPC

Abstract RU 2110478 C1

FIELD: inorganic chemistry, namely, extraction of vanadium of dead catalysts of sulfuric acid production. SUBSTANCE: acid solution being obtained after leaching of dead catalyst is initially neutralized with the help of alkaline reagent, the process is carried out to pH higher than 6.5. Then oxidation by passing oxygen through solution takes place. Vanadium is isolated as potassium and sodium polyvanadates, the process is carried out by adding acid till pH is 4.8-6.3. Method is realized in corrosion resistant medium. Oxidation with the help of air may be conducted in flotation device. EFFECT: improved efficiency of the method. 2 cl, 2 tbl
