Pressure Oxidation. Which leads us nicely to the gold standard for refractory processing POX. Although POX does carry significant CAPEX and OPEX costs, it can be harnessed to create significant value. One such example is Russian gold producer, Petropavlovsk.

Pressure Oxidation Gold Plant

Pressure oxidation . 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.1 The pressure oxidation process is used to prepare.

Oxidation can also be accomplished by the use of high-pressure reactors called autoclaves, in which the minerals in an aqueous slurry are treated at high temperature and pressure with oxygen-bearing gases. After oxidation is complete, cyanidation, as described above, is employed to solubilize and extract the gold.

A lower GSR can be tolerated if the flotation concentrate is amenable to direct cyanide leaching without the costly oxidation stage to release the gold from the sulphides. And on-site dor production avoids the off-site costs of transport and smelter charges, but usually with lower recovery flotation recovery then oxidation-leach recovery so.

Unfortunately such a flowsheet is complex and with the current gold and uranium price as well as the average grades in the tailings dumps, such a flowsheet would not be economically viable.

Energy Requirements For The Pressure Oxidation Of Gold

A variety of feed materials may be subjected to pressure oxidation of their sulfide content to liberate gold contained therein for later recovery by cyanidation. Energy is required to pump the feed slurry into the pressurized reaction vessel, to heat the slurry to the reaction temperature, to supply oxygen, and to agitate the slurry and disperse the oxygen.
