  • Pressure Oxidation Overview Sciencedirect
    Pressure Oxidation Overview Sciencedirect

    Pressure oxidation refers to the oxidation of sulfides, such as pyrite FeS 2 and marcasite FeS 2, at elevated temperature and pressure. Oxidation releases encapsulated gold grains from the sulfides and makes the oxidation residue of the ore or concentrate more amenable for gold recovery by cyanidation in a subsequent leaching step.
