Abstract: The petroleum and petrochemical industries produce considerable amounts of spent catalysts. The platinum group metals (PGMs) exhibit excellent catalytic activity. Their excellent selective and activity make them very effective catalysts. Catalysts, after a certain period of active life and regeneration cycles, are deactivated. The aim of the present study is to introduce and compare the wet-base (hydrometallurgy) methods used for extraction of platinum from spent catalysts. First, the principles of wet method and its kinds are introduced. Then, the previous experimental studies in which the extraction of platinum from autocatalysts and spent catalysts of chemical industries has been studied, are reviewed and compared in terms of operating conditions, materials, economic and environmental aspects.
