“…Shackleton et al (2007) observed a slight decrease in flotation recovery of sperrylite (PtAs 2 ) and palladoarsenide (Pd 2 As) in the presence of copper sulfate. The decreased flotation recovery was attributed to the preferential occupation of specific sites by Cu(OH) 2 species which inhibits the adsorption of xanthates.…”

“…Shackleton et al (2007aShackleton et al ( , 2007b showed that there is a significant difference in the flotation response between the tellurides and arsenides of Pt and Pd, with arsenides being characterized by a much slower flotation response, with a corresponding lower recovery to the concentrate. On the basis of this information, the PGM grade-recovery Fig.…”

Platinum-group minerals (PGM) typically occur in such low concentrations that quantitative mineralogical evaluation is difficult or impossible. The FEI Mineral Liberation Analyzer (MLA) system used by Vale Base Metals Technology Development has been successfully employed to produce large PGM datasets that are statistically robust. The MLA Sparse Phase Liberation mapping routine produces false-color images that accurately document mineral textures, including intergrowths between various platinum-group minerals and between PGM and other tellurides and sulfides. The MLA PGM search results can be used in conjunction with mineral compositions to calculate the distribution of platinum-group elements among minerals; the MLA PGM images can be used to produce model grade-recovery curves that can predict platinum and palladium recovery in mineral concentrator circuits.

“…A Malvern Mastersizer 2000 was used to obtain particle size distributions (PSD) of all the mineral samples used in the study and Figure 1 shows the PSD of the mineral samples used in this study. Batch flotation tests to determine the mass of entrained particles and water recovered, were carried out in a 650 ml flotation cell agitated at 200 rpm by means of a multi blade disc impeller at a tip velocity of 0.52 m/s, and an air flow rate of 1 litre/min using 25 g of the mineral and synthetic plant water (Shackleton et al, 2007). The pH was in the range 7-8 which was the natural pH of the system.…”
