Abstract—The acidic, alkaline, and soda leaching of spent petrochemical catalysts to extract vanadium oxide is studied. The most efficient reagent, its consumption, leaching time, and temperature of the pulp are chosen using experimental results. The degree of extraction of vanadium oxide to the solution has been achieved at a level of 80% for a solution of sodium hydroxide (200 g/L) as a reagent, the solid-to-liquid ratio S : L = 1 : 3, a pulp temperature of 100°C, and a process time of about 3 h.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
