QUANTITATIVE MASS BALANCE OF PLATINUM GROUP ELEMENTS IN THE KELLY LAKE Ni-Cu-PGE DEPOSIT, COPPER CLIFF OFFSET, SUDBURY

Microscale data to macroscale processes: a review of microcharacterization applied to mineral systems

“…The vast majority of the studies that use LA-ICP-MS analysis focus on the application of the method to determine the partitioning behaviour of trace elements in given mineral phases, with implications for ore-forming processes and metal recovery. LA-ICP-MS analysis using the spot mode was originally used in ore geology to determine the trace elements in a range of sulphide and arsenide minerals from various deposits types such as PGE and nickel-copper ores (Huminicki et al 2005;Barnes et al 2006;Godel et al 2007;Holwell & McDonald 2007;Godel & Barnes 2008;Dare et al 2010;Dare et al 2011;Pina et al 2012) and gold (Large et al 2007;Large et al 2009;Thomas et al 2011). More recent studies cover a wider range of deposits (lead-zinc, volcanogenic massive sulphide or iron oxide -coppergold deposits) and in most cases combine semiquantitative LA-ICP-MS mapping with quantitative spot analysis (Cook et al 2011;Cook et al 2013;Zhang et al 2014b;Duran et al 2015;Gadd et al 2015;Genna & Gaboury 2015;Lawley et al 2015;Meffre et al 2015).…”

Petrogenesis of the Platinum-Group Minerals

“…The Sudbury body is an atypical igneous intrusion in that it is believed to have formed from a melt sheet produced after a boloid impact, at ~1.85 Ga. It has been suggested by a number of workers that the Sudbury PGE occur as PGM, rather than in solid solution in base-metal sulfides (Cabri and Laflamme 1976;Cabri 1981bCabri , 1988Cabri et al 1984;Li et al 1993;Farrow and Lightfoot 2002;Huminicki et al 2005). Ford et al (2011) carried out a grade recovery exercise utilizing samples from Sudbury's Coleman and Creighton mines as natural examples.…”

Relationship between microstructures and grain-scale trace element distribution in komatiite-hosted magmatic sulphide ores

“…Over the past 10 years, the advance of laser ablation inductively couple plasma mass spectrometry (LA-ICP-MS) has made it possible to determine the in situ concentration of a range of minor and trace elements in magmatic sulphide minerals. Much of this work has focussed on platinum group elements (Ballhaus and Sylvester, 2000;Barnes et al, 2008;Barnes et al, 2006;Godel and Barnes, 2008;Godel et al, 2007;Hanley, 2007;Holwell and McDonald, 2007;Huminicki et al, 2005). More recently, a wider variety of elements were included in LA-ICP-MS analysis, such as Se, Bi, Te and As (Dare et al, 2010;Godel et al, 2012;Hanley, 2007;Piña et al, 2013;.…”
