The Platreef is located in the northern limb of the Bushveld Complex of South Africa. This reef consists of a complex assemblage of rock types, with pyroxenites, serpentinites and calcsilicates being the most abundant. The predominant PGMs are the tellurides, arsenides, alloys and sulphides. The Pt and Pd tellurides contribute between 20-45% of the PGMs present in the Platreef ore followed by the alloys (26%), arsenides (21%) and sulphides (19%). Flotation is used in the processing of the Platreef ore to separate the siliceous gangue from the platinum group minerals (PGM) and base metal sulphides. The PGE arsenide and telluride minerals are considered to be slow floating when compared to other PGMs as there is evidence of them reporting to the tailings.This thesis aimed to investigate the flotation behaviour of these minerals and presents results which characterise the surface properties of synthetic cooperite (PtS), vysotskite (PdS), sperrylite (PtAS2), palladoarsenide (Pd2As), moncheite (PtPd(BiTe)2 and PtTe2) and merenskyite (PdPt(BiTe)2 and PdTe2) and attempts to relate the flotation behaviour of the various minerals to these characteristics. 2014-07-31T11:14:10Z 2014-07-31T11:14:10Z 2007 Doctoral Thesis Doctoral PhD http://hdl.handle.net/11427/5403 eng application/pdf Department of Chemical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
