Chemists refer to the six heaviest elements in group VIIIA: Ru, Rh, Pd, Os, Ir, Pt; as platinum metals ( Cotton and Wilkinson, 1966 ). However, since the mid-1960s geologists have used the expression platinum-group elements (PGE) to refer to these elements. In igneous rocks Au and Ag frequently behave in a similar manner to the PGE, and the …

Platinum-group element concentrations in the Loolekop pipe are compared with concentrations in copper porphyry deposits as well as in the O'okiep Cu-Ni deposit, Namaqualand, South Africa (Fig. 9). The PRIMA-normalized diagram shows significant differences in PGE concentrations between copper porphyry deposits and rocks of the …

Geochronological and geochemical studies, including platinum group element (PGE) analyses, were undertaken on samples from the El Abra–Pajonal igneous complex, northern Chile, to investigate the magmatic evolution of the suite. ... The initial Cu-oxide reserve for the El Abra deposit at the commencement of mining in 1995 was 798 …

1 Introduction. Porphyry Cu-Au deposits associated with both alkalic (cf. MacDonald and Katsura, 1964) and calc-alkalic magmatism are variably enriched in platinum-group elements (PGE) and may constitute important unconventional sources of palladium (Pd).In a few examples, the PGE have been a valuable byproduct of Cu-Au …

The Jinbaoshan platinum group element-(Cu)-(Ni) deposit in southwest China is a sulfide-poor magmatic platinum-group element deposit that experienced multiple phases of post-magmatic modification.

This study investigates the whole-rock major, trace, and platinum group element (PGE) geochemistry, as well as zircon trace element geochemistry, of six porphyry Cu ± Au ore-bearing suites and three barren suites in the central and southeastern UDMA. ...

The Nova-Bollinger Ni-Cu-platinum group element (PGE) deposit in the Fraser zone of the Albany-Fraser orogen consists of two main orebodies, Nova and Bollinger, hosted by the same tube-shaped intrusion but having distinctly different Ni tenors of around 6.5 and 4.8 wt %, respectively. Nova is also higher in Pd, but Cu and Pt tenors …

1. Introduction. Platinum-group elements (PGE) are usually present in the ng/g up to the μg/g level in magmatic sulfide deposits (Cabri and Laflamme, 1976; Barnes et al., 2006; Godel et al., 2010).It is well known from experimental and empirical studies that IPGE (Os, Ir, Ru) and Rh tend to partition into monosulfide solid solution (MSS), whereas …

Experimental studies on binary, ternary and quaternary Cu–Fe–Ni–S systems are fundamental for the investigation of magmatic sulfide deposits, the main source of Ni, Co and platinum group elements (PGE). Previous experimental studies successfully formulated our general understanding of the evolution of magmatic sulfide systems but, …

Mafic-ultramafic intrusive complexes possess a considerable capacity for hosting Ni-Cu-platinum group element (PGE) sulfide deposits. However, the mapping of small outcrops over large areas by field surveys is time-consuming. In this study, WorldView-3 (WV-3) data with moderate spectral and very high spatial resolution were …

The mineralisation is Cu-, PPGE-, and Au-rich and IPGE-poor and the platinum group mineral assemblage is overwhelmingly dominated by Pd minerals; however, the bulk rock Pt/Pd ratio is around 0.8.

The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have similar physical and chemical properties and occur together in nature. The properties of PGE, such as high melting points, corrosion resistance, and catalytic qualities, make them indispensable to many industrial applications.
