Platinum Group Metals Home
Platinum Group Metals Ltd is a mining company focused on the production of platinum and palladium Our projects are located in the Bushveld Complex in South Africa, surrounded by 70% of the world’s platinum productionPlatinumgroup metals, that is, Pt, Pd, Rh, Ir, Ru and Os, are predominantly extracted from sulfide ores from South Africa and Siberia Their extraction always involves smelting followed by PlatinumGroup Metal an overview ScienceDirect Topics The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically, and anatomically similar The PGMs are the densest known What Are Platinum Group Metals (PGMs)?

Mineral Resource of the Month: Platinum Group Metals
The platinum group metals (PGMs) are among the rarest mineral commodities in Earth’s crust They include iridium, osmium, palladium, platinum, Beneficiation and recovery of platinum group metals (PGMs) from the major reefs involves a complex set of unit operations that has evolved greatly over the last few decades Over time, a number of interesting flowsheets have been developed for the concentration, separation and purification of PGMsExtraction of gold from platinum group metal (PGM) ores A conventional flotationsmelting 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 possibleRecovery of platinum group metals from oxide ores—TML
THE PRIMARY PRODUCTION OF PLATINUM GROUP
The six platinum group metals (PGMs) occur together in 58% of world PGM production takes place in South Africa1 not only for ore haulage but also to drive compressed all of the rest comes from Zimbabwe, Canada and the USA The primary production of PGMs represents the transfer of metal from below ground resource to above ground material The most important source of platinum group metals in the US has been at Goodnews Bay in Alaska These placer deposits produced about 545,000 troy ounces by dredging between 1927 and 1975 Return to Metal Ores Page: Precious and Base Metal Photos of Natural Platinum Ore, Platinum and Palladium ore deposit of platinum group elements (PGEs) is that associated with magmatic base metal sulfide minerals in layered mafic or ultramafic igneous intrusionsThe common association of PGEs with sulfide minerals is a result of processes of magmatic and sulfide liquid segregation and fractionation The mineralogicalA Review of the Behaviour of Platinum Group Elements
Leaching platinumgroup metals in a sulfuric acid/chloride
Abstract A leaching process was established based on the ability of platinumgroup metals to form stable chlorocomplexes in acidic chloride solutions Industrial catalyst losses were examined for the recovery of platinum, palladium, and rhodium by leaching with a mixture of sulfuric acid and sodium chloride to avoid using aqua regia or autoclave The formation of ore deposits of the platinumgroup elements (PGE) requires that their concentrations be raised about four orders of magnitude above typical continental crustal abundances Such extreme enrichment relies principally on the extraction capacity of sulfide liquid, which sequesters the PGE from silicate magmasOre Deposits of the PlatinumGroup Elements The dispersed form of platinum group metals in platinum ores found as infinitesimally small impurities enclosed in the crystal lattice of ore and rockforming minerals is of lesser importance Primary deposits of platinum ores are platiniferous complex sulfide and platinum chromite ores in a variety of forms with massive and disseminated structurePlatinum Ores Article about Platinum Ores by The

According to the International Platinum Group Metals Association (IPA), it can take as long as six months from initial mining activities to produce the final metal The process from extraction to final product involves crushing and milling the ore into fine particles, concentrating the particles using froth flotation followed by drying and A leaching process was established based on the ability of platinumgroup metals to form stable chlorocomplexes in acidic chloride solutions Industrial catalyst losses were examined for the recovery of platinum, palladium, and rhodium by leaching with a mixture of sulfuric acid and sodium chloride to avoid using aqua regia or autoclave conditionsLeaching platinumgroup metals in a sulfuric The formation of ore deposits of the platinumgroup elements (PGE) requires that their concentrations be raised about four orders of magnitude above typical continental crustal abundances Such extreme enrichment relies principally on the extraction capacity of sulfide liquid, which sequesters the PGE from silicate magmasOre Deposits of the PlatinumGroup Elements
