2007-5-16 pared to R, the ratio of these elements in the sulfide liquid is equal to that in the conjugate silicate melt. Since, for a given group of magmatic sulfides, PGE ratios do not change as functions ofR, partition coefficients for all PGE must be high, of the order of 105. Keywords: platinum-group elements, geochemistry, mag-

The platinum-group elements (PGE) tend to exist in the metallic state or bond with sulfur or other Group Va and VIa ligands, and often occur as trace accessory minerals in rocks. Combined with three isotopic systems that contain the PGE, these elements afford a unique view of early solar system evolution, planet formation and differentiation ...

2021-5-20 This paper offers the first-ever study of a local chromitite stringer (~ 2 cm wide) enriched in platinum-group elements (PGE) from the Kevitsa Ni-Cu-PGE deposit. Chromite forming this chromitite is rich in Cr2O3 (29.06 ̶ 37.17 wt%) and FeO (FeOtotal = 45.88 ̶ 56.06 wt%) and low in MgO (0.04 ̶ 0.91 wt%). The chromitite host an unusual set of mineral inclusions including: (1) platinum-group ...

Industrial and strategic significance of platinum group elements (PGEs)—Os, Ir, Ru, Rh, Pd, Pt—makes them irreplaceable; furthermore, some PGEs are used by investors as “safe heaven” assets traded in the commodity markets. This review analyzes PGEs from various aspects: their place in the geosphere, destiny in the anthroposphere, and opportunity in the economy considering interactions ...

The platinum-group elements (PGEs)—platinum, palladium, rhodium, ruthenium, iridium, and osmium—are metals that have similar physical and chemical properties and tend to occur together in nature. PGEs are indispensable to many industrial applications but are mined in only a few places. The availability and accessibility of PGEs could be disrupted by economic, environmental, political, and ...
More2016-6-30 The Platinum Group Elements (PGE: Osmium, Iridium, Ruthenium, Rhodium, Platinum, and Palladium), also known as platinum group metals and platinoids, are transition metals located in the d-block of the Periodic Table of Elements (Groups VIII, IX, and X, Periods 5 and 6).The atomic radii of the Os, Ir, and Pt subgroup, caused by the lanthanide contraction of the 4f group elements, are similar to ...

2018-12-10 The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically, and anatomically similar. The PGMs are the densest known metal elements. Exceptionally rare, the six metals naturally occur in the same ore bodies. They are highly durable and, due to their high value, often recycled, giving them long life cycles.

Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM). Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile.

The platinum group elements are pre-concentrated and separated from a large amount of matrix elements by Te co-precipitation. The detection limit of this method is 1–9 pg g −1 when 10 g of sample are weighed and 10 mL is the final volume used. Results obtained for the reference materials, WGB1,SARM7 and GBW07288-GBW07294, are in agreement ...
