Pressure oxidation technology for the treatment of refractory gold concentrates has been deployed in some countries. Shuiyindong gold deposit is one of the Carlintype deposits which is a typical difficulttotreat gold deposit, located in Guizhou province in western China. It was the first application of acid pressure oxidation in China.
It is performed in an autoclave at high pressure and temperature, where highpurity oxygen mixes with a slurry of ore. When the original sulfide minerals are oxidized at high temperature and pressure, it completely releases the trapped gold. Pressure oxidation has a very high gold recovery rate, normally at least 10% higher than roasting.
