An investigation into the floatability of platinum group arsenides and tellurides under varying collector and solution chemistries
… flotation, with most of the losses attributed to sperrylite (PtAs2). This study has investigated the use of collectors with greater electron-donating properties such as trithiocarbonate and thiourea collectors under the assumption that these collectors would bond more readily with the sperrylite …

An investigation into the flotation response of sperrylite (PtAs2) by comparative evaluation of crystal structure and bonding atoms
… group mineral (PGM) components in this ore is sperrylite (PtAs2), which has been found to be slow floating compared to the other PGMs and often reports to the tailings stream. Sperrylite comprises about ~21% of the platinum groups minerals (PGMs) in the Platreef ore hence, improving its …

An investigation of cyanide-based heap leaching for extracting precious metals from Platreef ore
… of the Pt in the ore is in the form a mineral sperrylite (PtAs2), which appears to leach slowly in cyanide as compared to other mineral forms such as certain tellurides and sulphides in the ore. Subsequently, efforts were made to investigate methods to improve the second stage leach process, in …

Surface characterisation and flotation behaviour of the platinum and palladium arsenide, telluride and sulphide mineral species
… 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.
