Rhodium is a frequent trace constituent in pentlandite, with concentrations ranging from ppm ( e.g ., <4–11.7 ppm...

... Branch, Russian Academy of Sciences, Novosibirsk. Pure iridium (for Ir), rhodium (Rh), ruthenium (Ru), chalcopyrite (Cu and Fe), synthetic FeNiCo (Ni), and synthetic Sb 2 S 3 were used as standards. The following X-ray lines were used: Cu K α, Ni K α, Fe K α, Ir L α, Rh L α, Ru L α, Os L β, Pt L α, Sb L...

... detection level (MDL), but a rhodium peak is observed clearly in the core of the Ir-(As)-rich zone of Fig. 3 d . These results indicate that strong interrelationships exist between Ir, Rh, Ni and As (and As:S ratio). In contrast, Co covaries sympathetically with S, and antipathetically...

... by tulameenite Pt 2 FeCu, which forms dendrites ( Fig. 8 f ). Under the action of S-enriched solutions, rhodium is bound in miassite, and copper forms Cu-containing sulfides—chalcopyrite and cuprorhodsite, which are replaced by anillite Cu 7 S 4 during the later hypergene transformation. Other thiospinels...

... of the Czech Geological Survey in Prague. Rhodium (99.99%), nickel (99.999%), and arsenic (99.999%) obtained from Sigma-Aldrich Co. were the starting materials for the synthesis. A carefully weighed sample was loaded into the high-purity silica tube and a tightly fitting silica-glass rod was placed on top...

Judging from the small number of published analyses, the element Rh may be considered a neglected element compared with the other PGE. Rhodium has no suitable long-lived radioactive isotope for γ counting and it has only one isotope. Type 1...
