PGM Recovery Systems Where Recycling Makes $ense

Feb 27, 2021 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 In the present study, a pyrometallurgical iron matte process was adopted to separate PGMs from spent catalytic converters. 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.

Recovery of platinum group metals from oxide ores—TML Process

A conventional flotation-smelting process has been proposed to recover the platinum group metal (PGM) values from the sulfide ores. With the development of a low temperature roasting, acidic bromine leaching process by The Minerals Laboratory of BHP Minerals, substantial PGM recoveries from oxide and mixed oxide/sulfide ores are now possible.
