  • Gold Ore Processing Sciencedirect

    Pressure oxidation of gold ores is therefore a pretreatment leaching step to enhance gold recovery. Although pressure oxidation of gold ores and concentrates does not directly recover gold in a strict sense of the above definition, it is an essential step to enable the gold to be recovered.

  • Valves For Gold Autoclave Pressure Oxidation Pox Metso

    Autoclave pressure oxidation POX is an effective pretreatment option when extracting gold from refractory ore bodies, such as pyrite and arsenopyrite. While gold processing plants are the most common utilizers of POX technology, the process can also be applied to other metals, like copper, zinc and uranium.

  • Pressure Oxidation Archives International Mining

    Pressure oxidation was selected as the most feasible processing technology for double refractory ores. It is able to achieve gold recoveries of 96 by utilising high temperatures, elevated pressure and oxygen to recover encapsulated gold, while conventional cyanidation methods would result in suboptimal recovery rates of 2040.
