The Reduction of Chrome in UG-2 Flotation Concentrate

2021-8-4  The South African platinum industry has advanced into an era of predominantly mining and processing Upper Group Two (UG-2) ore to extract Platinum Group Metals (PGMs). Flotation concentrates derived from processing UG-2 ore are typically characterized by high chrome contents (>3 wt.%) which are not amenable to conventional PGM smelters. The net effect of high chrome, inter alia,

2011-4-1  To recover these fines, investigation results of Feng and Aldrich (2004) on the Western Chromite Mines in South Africa, shows that maximum 95.6% of chromite fines can be recovered by using column flotation with the optimum conditions of parameters. Flotation recovery of many minerals decreases as the particle size decreases.
