Separation of Palladium, Platinum and Rhodium from Metallic Mixture by Selective Dissolution with Hydrochloric Acid Solutions Containing Oxidizing Agents

Extraction of platinum group metals from catalytic converters

“…Various techniques are applied to extract PGMs from catalytic converters [ 114 , [125] , [126] , [127] , [128] ], including pyrometallurgical and hydrometallurgical methods with subsequent element recovery [ 55 , 106 , 110 , [129] , [130] , [131] , [132] , [133] , [134] , [135] , [136] , [137] , [138] ], biological methods [ 139 , 140 ], leaching methods [ 109 , [141] , [142] , [143] , [144] , [145] , [146] ], solvometallurgical methods [ [147] , [148] , [149] , [150] , [151] ], molecular recognition technology [ [152] , [153] , [154] , [155] , [156] , [157] ] and biometallurgical methods [ [158] , [159] , [160] , [161] , [162] , [163] , [164] , [165] , [166] ]. These methods collectively ensure effective and eco-friendly processing of PGMs.…”
