A systematic review of sustainable gold extraction from …
High-pressure oxidation comprises the oxidisation of sulphide/carbonaceous gold ore at high pressure and temperature. Temperatures exceeding 200 °C and oxygen pressures above 2200 kPa are used to attain complete oxidation of the gold-bearing ore. Reaction rates can be very fast, and the technology is widely-accepted.

Flotation of a complex sulphide ore I. Cu Zn selectivity …
The Cu Zn selectivity shows a strong dependence on the pre-conditioning type and flotation gases for mild steel grinding, but not for stainless steel grinding. The best Cu Zn selectivity happens for the combination of 5% oxygen pre-conditioning and air flotation after mild steel grinding. It seems that galvanic reactions after or during the ...
