| Abstract: | In this paper,the process of pressure cyanidation after pressure oxidation pretreatment for one refractory gold ore of China is studied. The leaching rate of gold reaches over 92%.The pretreatment methods include acidic pressure oxidation,catalytic pressure oxidation and alkaline pressure oxidation. In addition,the mechanism and advantages and disadvantages of each method are briefly introduced.The result of pilot-plant test is better than that of the laboratory experiment. |
