    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

    At the plant of the Consolidated Murchison Co. in the Transvaal, South Africa, where a refractory high antimony gold ore is being treated, flotation and cyanidation of the flotation concentrates and tailings are being practiced. The association of the antimony and gold is very intimate, and during 1946, while the antimony recovery amounted to 70.6 per cent, only 62.7 per cent of the contained gold was extracted.
