  • Automotive spent catalysts treatment and platinum recovery

    The recovery of platinum from spent catalysts was examined. Platinum leaching was studied considering particle size, temperature, solid–liquid and HCl/HNO3 ratio effects. Many elements together with Pt were taken from a mixed spent catalyst sample. The main components of the leach liquor were Pt (1.84 g/kg cat) and Fe (0.94 g/kg cat). Platinum was separated from the leach aqueous solution by ...
