摘　　要：广东省某含碳高砷型难浸金精矿 ,常规氰化金浸出率仅为 15 .0 2 % ,通过采用细菌氧化技术 ,使硫化物包裹金暴露或解离 ,吸附金的有机碳被钝化 ,金浸出率达到 94 .4 1% ,获得了较理想的试验研究结果。By conventional cyanide leaching of the carbon bearing high arsenic refractory gold concentrate from a certain place of Guangdong Province,the gold leaching rate was only 15.02%.Through the use of bacterial oxidation,the gold wrapped by sulfide were liberated or exposed,the organic carbon which adsorbed gold were passivated and the gold leaching rate came to 94.4%.It was a satisfactory result.
