Pressure Oxidation(POX) is a process used to extractgold, copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes elevated temperatures (roughly 230 degrees Celsius), elevatedpressures(roughly 35 bar or 510 psi), and oxygen to liberate the minerals from refractory ores. POX has been used since 1985 when it was first put into commercial production at Homestake’s …Email:[email protected]
Theplantflowsheet has a conventional grinding circuit feeding an acid preconditioning circuit that destroys the carbonate minerals in the ore before feeding three parallel autoclaves. These hold the ore at 210 C (400 F) and 2.8 MPa (410 psi) for 90 minutes while oxygen from a 290 t/d (320 stpd) Air Products cryogenicplant…

ThePressure Oxidationfacility (‘POX Hub’) is a cornerstone of Petropavlovsk’s strategy and the principal driver of future value for the Company. The ability to process previously untreatable refractory ores, wheregoldis locked in sulphides, has opened a swathe of new opportunities for the Group to exploit both in the short and long term.
The São Bento Mine in Brazil was commissioned in 1986 and employed apressure oxidationcircuit to treat refractory flotation concentrate. The concentrate typically contained pyrite (16%), arsenopyrite (38%) and pyrrhotite (46%). Thepressure oxidation plant…
