The autoclave building will comprise two horizontal autoclave vessels. Image courtesy of Alacer Gold Corp. The Çöpler open-pit gold mine in Turkey is being expanded to introduce pressure oxidation method to produce gold from the refractory sulphide ore. The mine currently uses heap-leach operation to produce gold from the oxide ore. Definitive feasibility study for the expansion project was,Pressure Oxidation - Caldera Engineering,Overview. Pressure Oxidation (POX) is a process used to extract gold, copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes elevated temperatures (roughly 230 degrees Celsius), elevated pressures (roughly 35 bar or 510 psi), and oxygen to liberate the minerals from refractory ores.Summary of Gold Plants and Processes - ScienceDirect,01/01/2016· Pressure oxidation, roasting, CIL: 50% of gold in refractory carbonaceous sulfides. Sulfuric acid to remove carbonates before autoclave. Whole-ore acidic leach: 21: Mercur: USA: Fine gold with sulfides and organic carbon, carbonates: Pressure oxidation, CIL: Whole-ore alkaline leach owing to high carbonates: 21: Campbell: Ontario: High As and S,
