the platinum-group metals (pgms) consist of iridium, osmium, palladium, platinum, rhodium, and ruthenium. the pgms occur together in nature, but economic deposits are rare. pgms are produced from deposits that are mined primarily for pgms and are also produced as byproducts of nickel-copper mines.
Platinum is a chemical element with the chemical symbol Pt and an atomic number of 78. It is a dense, malleable, ductile, highly unreactive, precious, gray-white transition metal. Its name is derived from the Spanish term platina, which is literally translated into "little silver".Platinum is a member of the platinum group of elements and

May 15, 2011Platinum group elements (PGE Os, Ir, Ru, Rh, Pt, Pd) are important geochemical and cosmochemical tracers. Depending on physical and chemical behaviour the PGEs are divided into two subgroups IPGE (Ir, Os, Ru) and PPGE (Pd, Pt, Rh). Platinum group elements show strong siderophile and chalcophile affinity.
Geology and Mineralogy of NorthMet and the Duluth Complex. The NorthMet deposit is located in the Partridge River Intrusion of the Duluth Complex, a massive geological formation near the eastern end of the Mesabi Iron Range, which contains one of the world's largest known undeveloped accumulations of copper, nickel and platinum group metals.

Platinum. Platinum is a chemical element with Pt symbol and 78 symbol. It's a ductile, dense, maleable, highly unreactive, precious, silver-white transition metal. Its name comes from the Spanish platinum term, which means "little silver." Platinum is a member of the elements platinum group and group 10 of the elements periodic table.
New Ideas Paying Off for Platinum Group Elements at Waterberg Posted by Staff @ Geology for Investors in Mining Company News Reviews New discoveries based on new approaches and ideas are the holy grail for geologists, but they can often be a hard sell to management.
The concentrations of platinum-group elements (PGE), Co, Re, Au and Ag have been determined in the base-metal sulphide (BMS) of a section of the Merensky Reef. In addition we performed detailed image analysis of the platinum-group minerals (PGM).
May 10, 2015Abstract. The chromitites of the Bushveld Complex in South Africa contain vast resources of platinum-group elements (PGE); however, except for the economic upper group (UG)-2 chromitite seam, information on the distribution of the PGE in the ores and on the mineralogical nature, assemblages, and proportions of platinum-group minerals (PGM) is essentially missing.

Understanding the feed to processing operations is key to maximizing cash flow (economic value). Unfortunately the subject of economic geology is not covered within most undergraduate programs preparing students who enter the mining industry as process engineers. The good news is that there are reference materials available to help people learn these subjects.

Geological investigations in the Flin Flon greenstone belt oriented toward platinum group elements (PGE) focused on four related topics 1) A detailed investigation of the petrography and mineralogy of the McBratney Lake PGE-Au occurrence was carried out to elucidate the
commonly made to platinum-group metals and to platinum-group minerals, both often abbreviated to PGM. In this document we use PGM to refer to platinum-group minerals. Chemically the PGE are all very similar, but their physical . properties vary considerably (Table 1). Platinum, iridium and osmium are the densest known metals, being
The Reef contains an average of 10 ppm platinum group metals in pyrrhotite, pentlandite, and pyrite as well as in rare platinum group minerals and alloys. The Merensky and UG-2 reefs contain approximately 90% of the world's known PGM reserves. About 80% of the platinum and 20% of the palladium mined each year are produced from these horizons.
The bedrock geology of the Great Lakes basin can be subdivided into rocks of Precambrian and Phanerozoic and platinum-group elements deposits. Active Midcontinent rifting and its associated volcanism was followed by continued downwarping of the rift basin as it

The platinum-group metals (abbreviated as the PGMs) are six noble precious metallic elements clustered together in the periodic table.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 have similar physical and chemical properties, and tend to occur
The platinum group of metals comprises platinum, palladium, rhodium, iridium, osmium, and ruthenium, of which platinum is the most important. Of these metals, osmium is generally alloyed with iridium. The platinum group metals occur chiefly as natural alloys of various proportions and to a much lesser extent as sulfides and arsenides.
