Method For The Recovery Of Platinum Group Metals From Catalysts Comprising Silicon Carbide
Abstract: The invention concerns a process suitable for the recovery of platinum group metals (PGM) present in PGM-bearing catalysts comprising silicon carbide (SiC). More particularly, the process for the recovery of PGM present in PGM-bearing catalysts comprising SiC, comprises the steps of preparing a metallurgical charge by mixing the PGM-bearing catalysts with an Fe-oxide compound in an amount sufficient to oxidize at least 65% of the SiC, and feeding the metallurgical charge and slag formers to a smelting furnace operating in conditions susceptible to form a liquid Fe-based bullion, which contains PGM, and a liquid slag.Good to excellent PGM yields are obtained.
