The main platinum-palladium occurrence is in the Johns-Manville Reef (J-M Reef), an interval in the lower part of the Lower Banded Series. The Pt and Pd occur in intercumulate sulfides, typically pyrrhotite (Fe1-xS) and chalcopyrite (CuFeS2). Platinum ores in the J-M Reef are principally sulfidic anorthosites, but other lithologies also occur.
Stillwater igneous complex around Mouat chromite mine Chromitite with bronzite phenocrysts from Stillwater Igneous Complex Sulfidic serpentintite, platinum-palladium ore from the Stillwater Mine. This is an altered pegmatitic dunite very richly infused with intercumulate Pt/Pd-rich chalcopyrite & pyrrhotite (golden metallic minerals).
Platinum is a chemical element; it has symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish platina, a diminutive of plata "silver". [7] [8] Platinum is a member of the platinum group of elements and group 10 of the periodic table of ...
South Africa, with vast platinum ore deposits in the Merensky Reef of the Bushveld complex, is the world's largest producer of platinum, followed by Russia. [19] [20] Platinum and palladium are also mined commercially from the Stillwater igneous complex in Montana, USA. Leaders of primary platinum production are South Africa and Russia ...
A few other images are of low quality but it might be hard to find versions of higher quality: Ba (oxidises too easily), Pm, Ra, Pa (radioactives). A few images are only available as fair-use: Po, Np, Cm. It may be possible to find a free alternative (although it would be quite difficult).
This ore sample grades to around 2.5 ounces of Pd-Pt per ton of rock, with a Pd-Pt ratio of about 3:1. Another sample of Platinum-palladium ore from the Stillwater mine. The Stillwater mine and mill. Stillwater Mining Company (NYSE: SWC) is a palladium and platinum mining company with headquarters located at Littleton, Colorado, United States.
Rhodium is found in platinum or nickel ores with the other members of the platinum group metals. It was discovered in 1803 by William Hyde Wollaston in one such ore, and named for the rose color of one of its chlorine compounds.
Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded. [1] The demand for precious metals is driven not only by their practical use but also by their role as investments and a store of value. Historically, precious metals have commanded ...
