摘要:Abstract(#br)Two Ni-laterite profiles from the Loma Caribe peridotite (Dominican Republic) have been investigated for their platinum group element (PGE) geochemistry and mineralogy. One profile (Loma Peguera) is characterized by PGE-enriched (up to 3.5 ppm total PGE) chromitite...

摘要:Abstract(#br)Activation of sulphide minerals by copper sulphate is common practice on platinum group mineral (PGM) concentrators. However, the role of copper sulphate in the flotation of PGMs is still unclear especially in the case of those PGM ores which contain relatively low c...

摘要:Abstract(#br)Gold and platinum group minerals from the gold placers of the South Urals are studied in order to identify the metal sources. In placers from the Main Uralian fault zone (MUF), the primary gold contains Ag (up to 29 wt.%), Cu (up to 2 wt.%) and Hg (up to 4 wt.%)...

摘要:This paper develops sulfide calibration standards for quantitative determination of platinum group elements in natural sulfide-containing minerals by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). A series of sulfide calibration standards containing diff...

摘要:The relic minerals of the platinum group (MPG) were found for the first time in nephrite of tremolite–diopside composition associated genetically with the boninite dike of the Gorlyk-Gol deposit. This latter is confined to a segment of the zone of serpentinite mélange in the...

摘要:This study focuses on microinclusions of platinum group minerals (PGMs) in gold objects from the South Urals and North Black Sea archaeological sites. We demonstrate for the first time that melting of gold during archaeometallurgical work affects PGM microinclusions. Desquamatio...

摘要:... While whole-rock peridotite Re-Os isotopic signatures are the core of such investigations, the Re-Os dating of individual peridotite minerals—base metal sulfides (BMS) and platinum group minerals (PGM)—that are the main hosts for Re and Os in the mantle peridotites came...

摘要:Abstract(#br)A protocol for predicting recovery of platinum group minerals (GRPGM) is adapted from the protocol for gravity recoverable gold. This paper introduces the methodology to characterize the content of GRPGM in samples using the 3-in. (7.5 cm) laboratory Knelson concentr...

摘要:Abstract The chemical weathering of ultramafic rocks has resulted in eluvial concentration of Pt-group minerals (PGM) in lateritic weathering profiles of southern New Caledonia. The Pt mineralization interpreted as being primary consists of Pt-group minerals included within chr...

摘要:Abstract(#br)To more completely assess the primary magmatic origin of Ru–Os–Ir (IPGE) alloys, we conducted experiments to evaluate the effects of T, f O 2 , f S 2 and melt composition on the solubility of Ru in molten Fe–Ni–sulfide. Fe–Ni–S melt+Ru were held in oli...
