Metallurgical Test Work: Gold Processing Options, Physical

Jan 01, 2016 Certain gold ores, mainly those containing sulfides, arsenides, or tellurides, are best treated by producing a flotation concentrate (Anderson, 1980, Jones and Woodcock, 1984, King, 1982). This is almost always the case in treating refractory gold ores, where the refractory nature of the ore is due to sulfide mineral species.

Metallurgical testwork: Gold processing options, physical

Jan 01, 2005 Refractory gold ores. A range of treatment possibilities for refractory ores is now available, with many more being developed (Lorenzen and Van Deventer, 1992; Malhotra and Armstrong, 1996). The more accepted processes include: • Pressure oxidation: The conventional process operates at around 180–220°C at pressures in excess of 2,000 kPa
