merensky platinum processing

OVERVIEW OF PGM PROCESSING - Anglo American

2015-1-12  • The Merensky Reef, the source of most historical and current SA production, contains relatively higher PGM grades and ratios of Platinum (vs Palladium) • The UG2 Reef, a chromite-rich reef, is more consistent, but lacks Merensky’s high yield of Gold, Copper and Nickel byproducts.

2016-3-1  The PGE deposits of the Merensky Reef are strongly associated with base metal sulphide (BMS) minerals of copper, nickel and cobalt. The PGEs are present as either discrete platinum group minerals (PGM) included or attached to the sulphides, or in solid solution with the sulphides (Bulatovic, 2010, Osbahr et al., 2012, Wiese et al., 2006).

2021-7-6  The Bushveld igneous complex in northern South Africa has the largest deposit of platinum group elements (PGE) in the world. In trace amounts, these are closely associated with base metal sulphides (BMS). Froth flotation is used to beneficiate these PGE ores. The process constitutes a bulk sulphide recovery.

Platinum group metals in SA - Platinum Refineries

2020-1-17  There are minor differences in the details of the equipment and operations employed by the various producers. In Merensky processing a metallic concentrate rich in PGMs is sometimes produced in addition to the flotation concentrate. This concentrate can be sufficiently rich to by-pass the smelter and be sent straight to base metal removal.
