contact usPressure oxidation is one of the main methods used in the industry to improve gold recovery from sulfidic ores. During the autoclaving process, iron sulfides present in the ore are oxidized to ferric sulfate or other oxidized solid compounds such as hematite, thus liberating the gold particles and making them available for leaching.
