Extraction of Platinum Group Metals | IntechOpen
02-10-2017 · About 80% of the worlds’ reserves for platinum group metals (PGMs) are in South Africa’s Bushveld Igneous Complex. Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refinery. Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed, alternative routes to smelting of PGM are ...
Investigating Ways of Improving Recovery of Slow Floating ...
slow floating minerals in a single stage (MF1) Platinum Group Metal milling and flotation plant at the Zimplats Selous Metallurgical Complex. This study was conducted with an aim of improving flotation of PGMs by measuring the slow floating ratio (SFR) and analysing the effect on grade and recoveries as dosages of flotation reagents are altered.
pH Control in Flotation of PGM Platinum Group …

THE PRIMARY PRODUCTION OF PLATINUM GROUP METALS (PGMs)
PGMs are complementary and mutually-dependent. Annual PGM production is lower than the production of other metals; combined with the high production costs of PGMs, this results in highly economical and responsible usage. Primary and secondary production of PGMs create large revenues and thereby contribute greatly to the

Froth flotation - Wikipedia
04-03-2005 · Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
