Recovery of platinum group metals from oxide
A conventional flotation-smelting process has been proposed to recover the platinum group metal (PGM) values from the sulfide ores. With the development of a low temperature roasting, acidic bromine leaching process by The Minerals Laboratory of BHP Minerals, substantial PGM recoveries from oxide and mixed oxide/sulfide ores are now possible.

The PGM flotation predictor: Predicting PGM ore flotation ...
2015-5-18 The PGM flotation predictor predicts PGM recovery by produc-ing an output based on the physical properties of all PGM-bearing particles detected in the sample. These properties include mode of occurrence of the PGM (as per descriptions in Table 1), the float-ability of minerals associated with the PGM, liberation index (i.e.

The Importance of %Mass Pull in a Flotation Circuit
2013-7-25 The idea of selective flotation is to “concentrate” and put as much metal in as little a concentrate mass as possible. Pulling more mass has complicated process and mechanical implications as larger mass often cannot be handled by pumps or flotation cells for lack of volumes. For base metals plants/concentrators, a stage process that yields ...
