Hydrothermal remobilization platinum group elements and their secondary minerals in chromitite deposits of the Eastern Sayan ophiolites (Russia) [PDF]

E3S Web of Conferences, 2019
Serpentinization is an important post-magmatic process in spreading and subducted zones. This process is the cause of the remobilization and redistribution of highly mobile elements, platinum group elements (PGE) and base metals. Secondary platinum group

Platinum Group Elements Recovery from Used Catalytic Converters by Acidic Fusion and Leaching

Metals, 2020
The recovery of platinum group elements (PGE (platinum group element coating); Pd, Pt, and Rh) from used catalytic converters, using low energy and fewer chemicals, was developed using potassium bisulfate fusion pretreatment, and subsequently leached ...

Re-Os isotope and platinum group elements of a FOcal ZOne mantle source, Louisville Seamounts Chain, Pacific ocean [PDF]

, 2015
The Louisville Seamount Chain (LSC) is, besides the Hawaiian-Emperor Chain, one of the longest-lived hotspot traces. We report here the first Re-Os isotope and platinum group element (PGE) data for Canopus, Rigil, and Burton Guyots along the chain, which

Phase Analysis of Pt, Pd and Au in Black Rock-type Platinum Group Element Minerals by ICP-MS

Yankuang ceshi, 2017
Black rock as an important carrier of platinum group elements was discovered in recent years. Due to the multiple origins and complex mineralization, the distribution and occurrence of platinum group elements in black rock are not clear, which is also ...

Environmental Relevance of the Platinum-Group Elements [PDF]

Elements, 2008
Platinum-group elements (PGE) are used in an increasing number of applications, and emissions are resulting in elevated environmental concentrations of these normally rare metals. Automobile exhaust catalysts, which use Pd, Pt, and Rh as active components, are the main source of PGE emitted into urban and roadside environments, and they contribute to a
