Processing of weathered material from UG2 ore for recovery of Platinum group minerals (PGMs) is a challenging task due to poor recoveries and high chromite grade in the flotation concentrates. The flotation behaviour of the weathered and non-weathered ores of Middle Group 4 (MG 4) was investigated at different mining pit depths using sodium isobutyl xanthate as a collector, Sendep 30D as depressant and Senfroth 200 as a frother. The milling tests work were conducted prior to flotation. The results depicted that, t...
