In recent decades, significant investments have been made globally in the recovery and substitution of platinum group metals (PGMs), classified as critical raw materials (CRMs), necessitating the implementation of a circular economy model for efficient recovery. The extraction of PGMs from primary ores is costly due to the low concentrations (below 10 g/tn) and complicated extraction processes, whereas secondary resources, such as spent automotive catalytic converters, offer a more economically viable recycling alternative, providing over 57% of the European supply of PGMs. This review discusses various recovery methods, emphasizing that contemporary techniques aim for high recovery rates alongside cost effectiveness and environmental protection. Currently, pyrometallurgy dominates PGM recovery; however, hydrometallurgy is increasingly being selected, while biometallurgy is reserved for small-scale laboratory applications. The article highlights potential strides in hydrometallurgical recycling, which could enhance industrial scalability through the adoption of sustainable leaching processes characterized by milder conditions, environmentally friendly solvents, and greater volumes of solids leached. The discussion culminates in a reflection on the necessity of advancing hydrometallurgical methods to solidify their industrial relevance.
