An Investigation of the Role of Sodium Carbonate and Silica in the Neutral/Alkaline Pressure Oxidation of Pyrite

An Investigation of the Role of Sodium Carbonate and Silica in the Neutral/Alkaline Pressure Oxidation of Pyrite

Show other versions (1)

Pressure oxidation of refractory gold ores containing carbonate minerals is conducted under neutral/alkaline conditions in order to promote fast kinetics, reduced reagent consumption and suppressing the formation of elemental sulphur and CO2 (which reduces the effectiveness of the process). In this...
