Abstract
South Africa (SA) has a total of three reefs from the Bushveld Igneous Complex (BIC), which are mined and processed for the recovery of Platinum Group Elements (PGEs). The three reefs are Merensky, the UG2 and the Platreef (Mungall & Naldrett, 2008). The Platinum Group Minerals (PGMs) are mostly sourced from the UG2 reef because they are easy to recover as compared to Merensky and Platreef (Hey, 1999) by froth flotation. The froth flotation concentration process has been at the forefront in concentrating the PGMs from their perspective ores. Different concentrating circuits have been developed and these are aimed at floating mainly the sulfide minerals. Despite success in floating the sulfide minerals, significant complications are being encountered when it comes to floating weathered ores. Poor recoveries and high chromite grades are achieved when using the current conventional processing circuits due to complex mineralogy of oxidized ores (Becker, et al., 2014; Bulatovic, 2010; Cramer, 2001)...
