The first plant to treat UG2 ore on its own was commissioned atWestern Platinum Mine in 1984 (Brugman, 1985). Typically, concentrate containing -300 to 400 g/t PGE+Au and -3% Cr203 (Vermaak, 1995) is produced from UG2 ore by means of multistage size reduction and froth flotation. This concentrate is subjected to matte smelting, followed by a
[email protected]The concentrator studied processes ore from the UG2 platinum reef only – ore from the Merensky and UG2 reefs differ significantly in terms of mineralogy, therefore the focus is on UG2. UG2 ore has a higher chromite content, resulting in processing challenges, but can also contain higher concentrations of platinum group metals (PGMs)

Get Pricethe ore is milled, pelletised and normally sintered to produce a hard, competent pellet that is a suitable replacement for lumpy ore. Technology suppliers such as Outokumpu and Showa Denko typically supply these processes. Both these processes can use UG2 as part of their ore feed to the pelletising plants

Get PriceThe sulphide grains of UG2 ore are generally finer than those of the Merensky Reef. Merensky ore contains much more sulphide than does the UG2 ore, and the minerals are found in a silicate substrate, while UG2 ore has a chromite matrix. The Cr 2 O 3 content of the UG2 ore presents major challenges in processing
Get PriceNov 29, 2006 Thus, the UG2 is the second layer up-section within the upper group. Except for the UG1, the Upper Critical Zone chromitites are generally embedded in pyroxenite (locally they are underlain by anorthosite). The one that hosts the UG2 is ≈25 m thick and is hereafter referred to as the UG2 pyroxenite. Fig. 2
Get PriceJun 01, 2008 Platinum group minerals are recovered from the UG2 ore by industrial scale flotation and the challenge lies in presenting a liberated feed to the flotation circuit from a complex chromitite ore. Most of the mineral processing plants use crushers and tumbling mills
Get PriceJan 14, 2021 Reprocessing of UG2 secondary tailings for the recovery of additional PGMs after the extraction of chromite has become common practice for UG2 tailings operators. When chromite is recovered from UG2 tailings, the resultant waste material retains any PGMs that were “lost” during the initial processing of primary ore

About 60% of the run-of-mine is Bathopele product, the other 40% is railed from the other Rustenburg operations,” says Ratau
Get PriceUG-2 Ore UG-2 ore is the second most mined source of PGE in the Bushveld Complex. Located in a reef close to and largely parallel to the historically-mined Merensky Reef, UG-2 has always been an enticing source of PGE, but metallurgical difficulties delayed its extraction and processing until relatively recently.
