| Abstract: | Taking the gold ores from Gansu Pingding Gold Mine as the research object,by the way of domestication of moderate thermophile bacteria,the bacterial oxidation and cyanide leaching of the ores are performed under various technological conditions.Test results obtained proved that moderate thermophile bacteria have the ability of catalystic oxidation for the ore containing realgar,orpiment,pyrite,arsenopyrite.At the same time,the dearsenifying principle of As-containing sulphide ores under the action of bacteria is briefly discussed,and major factors influencing bacterial oxidation process are also analyzed. |

| Keywords: | Moderate thermophile bacteria Bacterium leaching As-containing sulphide ore |
