Anthropospheric Losses of Platinum Group Elements

2013
The platinum group elements are among the rarest elements in the Earth’s crust yet each plays an important role in modern society. Despite their technological importance, little has been published on how much is lost during their extraction, processing, use and recycling. This chapter provides estimates of global losses of Pt, Pd, Rh, Ru and Ir at each

Some facts on the platinum-group elements

International Review of Financial Analysis, 2017
The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium, and osmium. In this article, we concentrate on the dependency structure and economic determinants of PGE, silver, and gold prices. We find that the strongest relationship is between silver and gold returns at a weekly frequency (July 1992–July 2016), which ...

Platinum-Group Element (PGE) Deposits

2000
The platinum-group elements (PGE) comprise a geochemically coherent group of siderophile to chalcophile metals that includes osmium (Os), iridium (Ir), ruthenium (Ru), rhodium (Rh), platinum (Pt), and palladium (Pd). Based on association, the PGE may be divided into two subgroups: the Ir-subgroup (IPGE) consisting of Os, Ir, and Ru and the Pd-subgroup (

Platinum Group Elements in Canadian Coal

Energy Sources, 1990
Abstract 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 ...
