Abstract

Abstract

The waste catalyst from acid production from heavy metal smelting flue gas has relatively complex impurity compositions. In order to obtain the optimum conditions for comprehensive recovery of vanadium, potassium and zinc from the waste catalyst, a direct leaching process was proposed and the factors affecting the leaching rate of vanadium, potassium and zinc, e.g. the mass fraction of leaching agent, liquid-solid ratio, reaction temperature and time, were studied. The chemical and phase compositions of the waste catalyst and leaching residue were analyzed and compared. The optimum leaching conditions were determined at the sulfuric acid mass fraction of 8%, liquid-solid ratio of 2∶1, leaching temperature of 70 ℃ and leaching time of 1.5 h, with the leaching rates of vanadium, potassium and zinc at 93.58%, 85.43% and 99.31%, respectively. The proposed process is better than the traditional roasting method.
