1. Introduction. It is well known that Ni-Cu-platinum-group elements (PGE) sulfide deposits, particularly those hosted by komatiites, are likely derived from the melts by high degrees of partial melting of the sublithospheric convecting mantle (Naldrett, 2004, Maier and Groves, 2011, Arndt, 2013).However, Ni-Cu-PGE sulfide deposits may be also …

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, …

Platinum-group elements have been widely used to constrain the sulfide saturation history and the interaction between sulfide and silicate magmas in the formation of magmatic Ni–Cu–(PGE) sulfide deposits (Barnes and Maier 1999; Naldrett et al. 2000; Song et al. 2008; Wang et al. 2011). In this contribution, we use Re–Os isotope …

Here, OH330 is a thinly layered horison that lies among the host olivine orthopyroxenite. It consists of interlayers of dunite, harzburgite, and orthopyroxenite containing fine sulfide dissemination with increased contents of Ni (1290–5220 ppm), Cu (up to 2320 ppm), and platinum group elements (PGE) (0.43–1.40 ppm of the PGE tot).

Platinum group metals (PGMs) are primarily used in automotive exhaust catalysts (autocatalysits). Spent autocatalysts are the most important secondary resource for PGMs. However, transporting autocatalyst scraps and recovering PGMs from the scraps are costly and time-consuming, owing to the low PGM content in spent autocatalysts. …

Platinum group metals (PGMs) are recovered using molten Cu or Pb as collector metals during pyrometallurgical recycling processes. The collector metal containing PGMs is oxidized to produce a PGM-enriched alloy and slag, primarily containing Cu or Pb oxide. Additionally, the slag comprises a considerable amount of PGMs. Therefore, it is …

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 …

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 …

The Ni–Cu–Platinum Group Element (PGE) sulfide deposits of the Sudbury Structure have provided a major portion of the world's total nickel production and their host rocks have been the subject of numerous research studies, yet a number of perplexing problems remain to be solved. On the one hand, studies seeking to explain the formation …

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 …
