While the solubility of this complex makes sulfuric acid a desirable leaching agent, nitric and hydrochloric acid can also be used, but are typically not due to their higher cost and corrosiveness. After leaching, the leach liquor must normally undergo concentration of the metal ions that are to be recovered. This paper presents a promising hydrometallurgical process to recover precious metals . Many of these technologies are part of Metsos Planet Positive offering. Resour. In this study, we performed a hydrometallurgical process through soda roasting and water leaching for the recovery of vanadium (V) and tungsten (W) from spent SCR deNOx catalysts. With the continuous increase in demand for metals due to the depletion of ores, recycling of this waste is becoming an attractive alternative. Similarly, autoclaves enable the use of gaseous reagents in the system. The two traditional ways of lead recycling and recovering are pyrometallurgy [ 2, 3, 4] and hydrometallurgy [ 4, 5, 6, 7 ]. Due to the environmental risk that spent SCR catalyst pose when discarded in landfills and the presence of valuable metals such as vanadium and tungsten, there is a big necessity for recycling of these secondary resources.
