processing refractory gold ores, especially development in the pretreatment of refractory gold minerals by nitric acid. These processes include the highpressure and the atmosphericpressure oxidation methods. Highpressure oxidation processes are difficult to carry out, because they require highcapital cost autoclaves.
#0183;#32;Sulphur oxidation The results of pressure oxidation and cyanidation tests [7] are given in Figures 4 to 8. These results show that the recovery of gold after pressure oxidation is proportional to the sulphur oxidised, suggesting the Pretreatment of refractory gold concentrates 869 amenability of pyritic sulphur to oxidation.
High Pressure Oxidation of Refractory Gold Minerals A lot of researches deem this process as the best option to the treatment of refractory material that contains gold and silver, primarily when the precious metals are
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.

Pressure Oxidation is a process for extracting gold from refractory ore.. The most common refractory ores are pyrite and arsenopyrite, which are sulfide ores that trap the gold within ores require pretreatment before the gold can be adequately extracted. The pressure oxidation process is used to prepare such ores for conventional gold extraction processes such as cyanidation.

Pressure Oxidation Pressure oxidation is employed to liberate gold and silver in refractory sulfide concentrates often and ores. The main pressure oxidation products from iron sulfide minerals are sulfuric acid (and metal sulfates) and hematite. Depending on the conditions within the autoclave, acid containing iron compounds can be formed.
