Gold Mining Companies That Use Pressure Oxidation Plants

Jul 24, 2020 With the oxide component nearing depletion in May of 2019, the Copler sulphide plant, which uses pressure oxidation, declared commercial production. This year, the company expects to churn out 80,000 oz. to 100,000 oz. gold from the oxide plant with a further 230,000-260,000 oz. expected from the sulphide plant at consolidated AISCs of US$735.
