platinum group ore processing - vukanimaafrica.co

Platinum group metals are unevenly distributed within deposits of platinum ores. Their concentrations range from 2–5 g to several kilograms per ton in primary platinum ores, from tenths to hundredths (sometimes thouhs) of grams per ton in primary complex ores, and from tens of milligrams to hundreds of grams per cu m in placer deposits.

Direct leach approaches to Platinum Group Metal

2015-7-1  Platinum group metals are conventionally recovered from high-grade concentrates (typically assay of 200 to over 2000 g/t PGM with 0.4–2.8% Cr 2 O 3) by the traditional matte–smelting–refining technique depicted in Fig. 2 (Cole and Joe Ferron, 2002).Ore is first ground by conventional multistage crushing and ball milling, or by semi-autogenous grinding (SAG), and then smelted.

Methods of recovering platinum-group metals from ...

Because the ore is sulfidic in nature, it was concentrated by froth flotation. A 45 kg/h process development unit (PDU) was constructed and 85 to 95% of the platinum and palladium were recovered from the ore by using mercaptobenzothiazole or sodium isobutyl xanthate as collectors.

Extraction of gold from platinum group metal (PGM)

2005-1-1  The major reefs mined today are the Merensky, UG2 and Platreef, with ore grades ranging from 3 to 8 g/t PGM and with associated nickel and copper in the 0.1–0.2% range present mainly as sulfides. Merensky reef has been the principal source of PGMs, and as demand for rhodium increased from the late 1970s exploitation of the UG2 now accounts for about half of the ore mined.
