With the help of water-acid leaching methods, studies were carried out on the extraction of vanadium (V) oxide from spent vanadium-containing catalysts of Maksam-Chirchik JSC, AGMK JSC and Ammophos-Maxam JSC. A new, resource-saving technology for the extraction of vanadium compounds from spent vanadium catalysts has been proposed. In order to reduce the consumption of sulfuric acid in the leaching process, a three-stage aqueous acid leaching was proposed, as a result of which the degree of extraction of vanadium into the solution is more than 98%.
