METHOD OF MATERIAL PROCESSING, MAINLY, CONTAINING NICKEL, COBALT, MOLYBDENUM, VANADIUM IN NONORGANIC, FOR INSTANCE, OXIDE BASE

摘要

FIELD: hydrometallurgy, particularly, leaching of material with nonorganic base containing nickel, cobalt, molybdenum, vanadium applicable in process of spent catalysts. SUBSTANCE: method includes leaching of solid initial material having specific surface of 1000-100000 sq.m/kg placed in liquid reaction solution with the following requirements: 0.5 (liquid-solid) 10 (by weight). Novelty consists in application of electric current, preferably, alternating current to obtained reaction mixture with current density of 1-10 A/sq.dm and voltage of 1-4 V/cm. EFFECT: accelerated dissolving and increased concentration of useful components in solution. 3 cl, 1 tbl
