  • PGM Recovery Systems Where Recycling Makes $ense

    Nov 18, 2020· History. PGM Recovery Systems, Inc. entered the PGM recycling space in 2010 in an effort to overcome the volume processing of scrap oxygen sensors. This took our engineering team six months to resolve. Beside the scrap sensor technology, in 2017 we tested, proved, and implemented a new technology to overcome the extraction of a low value PGM feed stock.

  • A new approach to recover platinum-group metals from spent

    Aug 01, 2020· PGM recovery using the classical iron smelting process requires very high temperatures (~2000 °C), but the smelting temperature used in this process was less than 50% that of the classical process. The influences of the B 2 O 3 /Na 2 O ratio, S/Fe ratio, iron source, reaction temperature, and reaction time on the recovery of PGMs from

  • Automotive exhaust catalysts: PGM usage and recovery

    One of the most important and well-known examples is the conversion of the pollutants generated by the combustion of fuel to non-toxic products. The significance, supply situation and the recovery processes of the precious metals used as catalysts — platinum, rhodium and palladium (hereafter referred to as PGM) — are described.
