Platinum-Group Element Deposits in Layered Intrusions: Recent Advances in the Understanding of the Ore Forming Processes

“…9.15) or secondary magnetite observed within the reefs. In these minerals, the PGE are only found as discrete PGE-rich phases mainly Pt-rich in the Merensky Reef (Ballhaus and Sylvester 2000;Godel et al 2008;Osbahr et al 2013), Pd-rich in the J-M Reef (Godel and Barnes 2008a) with minor Ru, Os, Ir (probably laurite) in both cases. Although to date no data are available for other deposit, it seems improbable that chromite and spinel in general contribute significantly to the PGE mass balance in PGE reefs.…”

“…Recently, homogeneous Ru laser ablation ICP-MS spectra in chromite from komatiites have been interpreted as evidence of partitioning of the IPGE in solid solution within natural chromite crystals (Locmelis et al 2011;Pagé et al 2012). Several laser-ablation ICP-MS analyses have been carried out on chromite crystals from the Merensky Reef of the Bushveld Complex (Ballhaus and Sylvester 2000;Godel et al 2008;Osbahr et al 2013), and on chromite and secondary magnetite grains of the J-M Reef of the Stillwater Complex , in order to test whether the PGE partitioned into natural spinel phases in sulfide-rich PGE-reef environments. The results of all of these studies indicate that none of the PGE are present in detectable (i.e.…”

“…b Base-metal and platinum-group element concentrations of coarse-grained (i.e pegmatoidal) melanorite and melanorite from the Merensky Reef. The data are extracted from Godel et al (2007), Barnes and Maier (2002b), Naldrett et al (2009b) and Osbahr et al (2013). c Base-metal and platinum-group element concentrations of pyroxenite from various localities within the Platreef.…”

Analysis of Platinum Group Elements in Environmental Samples: A Review

“…Alternatively, Te co-precipitation for Pt detection (Zereini et al 2012) and Hg co-precipitated for Pd (Alsenz et al 2009;Zereini et al 2012) were described in combination with ID-ICP-MS determination in airborne particulate matter. A direct method for PGE quantification in solid samples is laser ablation ICP-MS. Well homogenized solid rock samples can successfully be analyzed as shown by Gilbert et al (2013) and Osbahr et al (2013) …”

PGE Production in Southern Africa, Part I: Production and Market Trends

“…The Bushveld Complex is the only location where reef-type PGE deposits (Merensky and UG2 reef type) and contact-type Cu-Ni-PGE deposits are mined. Apart from PGEs, notable quantities of Ni, Cu, Co, Cr, Au and small amounts of Ag, Sb, Bi, and Te can be recovered [55][56][57][58][59][60][61].…”
