  • Pressure Oxidation Mining SGS

    Pressure oxidation (POX), high pressure oxidation (HiPOX) and ACTIVOX autoclave leaching are viable industry-standard technologies used to recover gold and other accessory metals. The process is particularly well suited for treating refractory gold ores, which give low recovery when directly leached with cyanide.

  • Pressure oxidation Wikipedia

    Pressure Oxidation is a process for extracting gold from refractory ore. The most common refractory ores are pyrite and arsenopyrite, which are sulfide ores that trap the gold within them. Refractory ores require pre-treatment before the gold can be adequately extracted.
