Alkaline Pressure Oxidation of Pyrite in the Presence of Silica – Characterization of the Passivating Film
Alkaline pressure oxidation, particularly in the presence of trona as additive, can be used to oxidize high carbonate refractory gold ores as it prevents the formation of CO2 in the autoclave. However, the presence of silica in the ore can lead to the encapsulation of pyrite due to the formation of...
