PERSPECTIVES ON PLATINUM GROUP ELEMENTS
La Chimica e l'Industria, 2023Platinum Group Elements (PGE), a group of metals with unique physico-chemical and catalytic properties, are used in different strategic technologies and their importance in modern chemical industry is outstanding. The present article aims at a concise update concerning main current and future uses, production, resources, and recycling prospects.

Platinum Group Elements Mineralization
2020Platinum group element (PGE) mineralization is associated with ultramafic and mafic rocks. There are three major types of PGE mineralization in Mongolia. The most common is (1) PGE mineralization related to ophiolites and includes podiform chromite, (2) PGE in layered gabbro intrusion, and (3) PGE-Au placer.

An Examination of Platinum-Group Element Thiospinels
The Canadian Journal of Mineralogy and Petrology, 2023Abstract A review and discussion of platinum-group element thiospinels is presented, the context of which is a proposal accepted by the Commission of New Minerals, Nomenclature and Classification (voting proposal 17-H) made for the redefinition of cuproiridsite (ideally CuIr2S4), cuprorhodsite (ideally CuRh2S4), and malanite (ideally ...

PLATINUM GROUP ELEMENT HIGH-ENERGY PIXE
International Journal of PIXE, 1990K X-ray spectra have been obtained from Platinum-Group Element (PGE) minerals using 40 MeV Proton-Induced X-ray Emission. It is possible to resolve all four component X-ray lines for the PGEs. In cases where there is more than one PGE present, some K X-ray lines may overlap, but in all cases, there were single lines available for quantitative analysis.

Platinum-Group Elements in Cosmochemistry
Elements, 2008In a cooling solar nebula, five of the six platinum-group elements (PGE) condense as refractory-metal alloys at temperatures above the condensation of Fe-Ni metal. Non-refractory Pd condenses in solid solution with Fe-Ni. Such refractory alloys are preserved in some meteorites, although they are often highly altered.

1993
Platinum group elements are ruthenium, rhodium and palladium (of similar weight as, but lighter than silver, the next element in the periodic table by atomic number) and osmium, iridium and platinum (of similar weight as, but lighter than gold, the next element in the periodic table by atomic number). As opposed to gold and silver, known probably since

Platinum group elements in seawater. I. Palladium
Canadian Journal of Chemistry, 1983Palladium was coprecipitated quantitatively from seawater with an added bismuth carrier precipitated as a sulfide. The 109Pd formed upon neutron irradiation of the isolated material was measured by γ-ray spectrometry following radiochemical purification.

Platinum Group Elements in Canadian Coal
Energy Sources, 1990Abstract Platinum group element (PGE) concentrations in seven Cretaceous and Tertiary coal deposits in Canada were determined using plasma mass spectrometry, neutron activation analysis, and direct current plasma spectroscopy. PGE concentrations are generally below detection limits; however, elevated values were determined in Quintette (100 to 1 ...

P81 Occupational hypersensitivity to platinum group elements
Contact Dermatitis, 2004Objective: the increasing industrial use of platinum–group elements (PGEs), namely Ir, Pd, Pt and Rh and related hypersensitivity such as respiratory symptoms, urticaria and contact dermatitis, have led to a growing need to monitor selected populations of exposed workers.

Ore Deposits of the Platinum-Group Elements
Elements, 2008The formation of ore deposits of the platinum-group 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 magmas.
