THIOUREA LEACHING OF GOLD IN A CONTINUOUS PILOT PLANT ...

Overview. 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.

Gold Leaching Pilot Plant

A fully integrated pilot plant was operated at the Mount Lyell Copper Mine in Tasmania, Australia, treating a high-grade chalcopyrite concentrate. Copper extraction was over 90 per cent, and the leach liquor was purified by SX-EW to produce premium-grade cathode copper.
