  • 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.

    Another area that feeds this myth concerns the recovery and refining process itself: the methods and procedures that ultimately extract the remaining precious metals from spent catalyst lots. Two methods for PGM recovery Precious metals refiners typically use one of two methods to recover and refine platinum group metals (PGMs) from spent

  • Recycling the Platinum Group Metal (PGM) Refining Process

    Global Refining Group: Leading the US With Our PGM Processing System. At Global Refining Group,we are confident that our processing system is the most effective method of PGM recycling in the United States and around the world.

  • The Effective Technological Processes for PGM Recovery

    More than 80% of PGM mineral grains has size less than 100 microns, that determines the possibility of significant losses of platinum in the process of gravity separation and the need for additional recovery processes for small and fine fractions of platinum tailings and sludge products. Summarized results of laboratory tests of small-volume

  • Recovery of PGMs from an oxide ore by flotation and leaching

    has triggered interest in exploration of techniques for PGM recovery from near surface oxidised PGM ores. All earlier attempts to process the oxidised PGM ores by conventional flotation methods achieved poor recoveries (typically less than 50 %) hindering the commercial exploitation of these resources.

  • Recovery of platinum group metals from spent catalysts: A

    Dec 10, 2015· In the process, organic substances volatilization and phase constitution change will easily lead to low PGM recovery, environmental pollution and complex subsequent process. Choosing feasible treatment condition is extremely important according to the properties of the spent catalyst.

  • The recovery of platinum group metals from low- grade

    Currently, the matte-based collection process is the most widely used for PGM recovery, but because increasing amounts of UG2 concentrates are being processed, it is expected to be integrated with or replaced by an alternative processes. Mintek has developed an alternative process, known as the Conroast process, for smelting PGM-containing
