Identification of platinum ores via trace element signatures [PDF]

open access: yes, 2011
This project studies the natural variation in the elemental composition of processed platinum ore from different extraction locations in South Africa in order to assess whether this provides sufficient information for the elemental fingerprinting" of the

PLATINUM-GROUP MINERALS IN PODIFORM CHROMITITES OF THE OMAN OPHIOLITE [PDF]

open access: yesThe Canadian Mineralogist, 2003
Chromitite lenses rich in the platinum-group elements (PGE) have recently been discovered in the deeper part of the mantle section of the northern part of the Oman ophiolite. In terms of stratigraphic level, there are two types of chromitite: Moho transition zone (MTZ) and mantle types.

New mineralogical data on platinum-group minerals from the Río Santiago alluvial placer, Esmeraldasprovince, Ecuador [PDF]

open access: yes, 2020
Mineralogical studies on platinum-group minerals found in placer deposits from the Río Santiago (Ecuador) are scarce. In this investigation, one sample collected from the Río Santiago alluvial placer was studied via a multi-disciplinary approach ...

Platinum-group minerals and their host chromitites in Macedonian ophiolites [PDF]

open access: yesEuropean Journal of Mineralogy, 2017
Several ophiolite bodies that have been a significant source of chromium ore are located in the Vardar Zone of Macedonia. Three relatively small (maximum 15 × 4 km) bodies have been studied in detail. In the Radusa and Lojane complexes, the mantle series consisting of harzburgite and rare dunite are well preserved, whereas minor pyroxenite and gabbro ...

Ti-Fe-Cr spinels in layered (stratified) complexes of the western slope of the Southern Urals: species diversity and formation conditions

open access: yesЗаписки Горного института, 2022
Materials on geochemistry and ore Fe-Ti-Cr mineralization of rocks composing layered (stratified) bodies of the western slope of the Southern Urals are presented. A detailed analysis showed similarity in the redistribution of REE, noble metals, and Fe-Ti-

How and when do Pt- and Pd-semimetal minerals crystallize from saturated sulfide liquids?

open access: yesFrontiers in Earth Science
Platinum and Pd-arsenides, antimonides, tellurides, bismuthinides, and sulfides are the major hosts of Pt and Pd in magmatic and hydrothermal Cu-Ni-sulfide ores.

INTERGROWTHS OF PLATINUM GROUP MINERALS FROM THE MIASS PLACER ZONE (SOUTH URALS) AND THEIR PRIMARY SOURCES [PDF]

open access: yesМинералогия, 2016
Twenty four platinum group minerals (PGMs) were found in the Kialim and Maly Iremel gold placers of the Miass placer zone, South Urals. Rhodarsenite, bowieite, cuprorhodiste, and xingzhongite(?) were found in the Urals for the first time.
