Pgm refining. As the largest secondary platinum group metals (pgm) refiner in the world, we've developed highly advanced processes for extracting and separating pgms from products – so advanced that we can refine pgms to a purity of 99.95%. We work with our customers to optimise precious metals recovery from complex materials and our,Extraction and Refining of the Platinum Metals | Johnson,,The platinum group metals, together with some gold, total about fifty ounces to the ton. The complete process of extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the individual platinum group metals from each other, followed by final refining. Operations to achieve this can,Platinum Refineries - buyers of Platinum, Rhodium,,Platinum Refineries is a division of Northern Refineries, designed exclusively to meet all your Platinum group metal refining needs.

These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6). The six platinum-group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum. They ha…Industrial - Petroleum - PMM,Other platinum group metals. Palladium is used by a limited number of refiners for upgrading certain refinery feeds in a process known as hydrocracking. Iridium can also be used in conjunction with platinum in a few niche reforming applications. Platinum catalyst. Reforming and isomerisation processes use catalysts made by coating platinum onto an alumina substrate in the form of smallRecycling the Platinum Group Metals: A European,,The high technical recyclability of platinum group metals means that over 95% recovery can be achieved once pgm-containing scrap reaches a state-of-the-art refining facility. Technical challenges exist, but the main barriers to recycling pgms lie in ensuring the collection of scrap and in the capacity and technical capabilities of recycling chains around the world.Pgm refining | Johnson Matthey,Pgm refining.

Methods include electrolysis, wet chemical chlorination (aqua regia), and wet chemical parting. All mine doré and scrap material can be refined up to '999.99' (five-nines) purity, to meet specific industrial needs such as electronics and fine jewelry manufacture. After refining, gold, silver, platinum or,PRODUCTION AND USES OF PLATINUM GROUP METALS,CHAPTER 3 | PRODUCTION AND USES OF PLATINUM GROUP METALS 3.2 PRIMARY REFINING PROCESSES In primary PGM production, ores from the major deposits all go through a similar series of initial process stages involving crushing, milling, and froth fl otation to produce a base metal-PGM concentrate.
