In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals. In order to achieve …

Flotation and leaching were investigated as possible processing routes for improving PGM recovery from a Southern African oxidized PGM ore. Different flotation reagent schemes and lixiviants were evaluated and their PGMs extraction response measured. Characterization of the PGM ore used in this study indicated that it was enriched in oxide ...

The use of alkaline pressure oxidation to pretreat refractory gold ore often results in insufficient gold recovery (<60%) in downstream thiosulfate leaching. To improve gold recovery, flotation was considered for the separation of carbonaceous matter (C-matter). In this study, the effect of MIBC on C-matter flotation was investigated to …
