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. POX has been used since 1985 when it ...

Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.

High pressure grinding roll - saving energy and providing results. The HPGR truly is a unique comminution product. It weakens rock structure and exposes ore particles, making it an attractive option for heap leach applications.
