A process is disclosed for recovering platinum group metals from a spent catalytic member, and in particular, from a catalytic converter from an automobile. The process comprises comprising introducing the catalytic member (10) into a reaction chamber (10), wetting the spent catalytic member with an acidic solution of hydrochloric acid, heating the reaction chamber and adding an oxidizing agent, such as HNO3 and H202, continuing heating such that gaseous vapors are produced and caused to circulate through the reaction chamber, and condensing the gaseous vapors so as to obtain a solution containing platinum group metals from the spent catalytic member. Also disclosed is a reactor adapted for performing the recovery process. The reaction chamber (5) comprises a condenser (2) and is advantageously placed in a heating chamber (4) filled with oil (8). Preferably the catalytic member (10) is disposed in a receptacle (11) having a perforated bottom (7). |
