| 中文摘要: |
| 碳质金矿是一种难处理金矿，当原生矿石中有机碳含量大于0.2%时，会严重干扰氰化提金，进而发生“劫金效应”。生物预氧化法以其条件温和、工艺简便、能耗低、环境友好等优点在难处理金矿预处理方面发展较快。难处理碳质金矿生物预氧化法目前还处于研究阶段，要实现工业化需要从新型添加剂以及开发构建既能氧化硫砷又能氧化碳的新型细菌等方面进行研究。 |
| 英文摘要: |
| Carbonaceous gold ore is a kind of the refractory gold ores. The organic carbon will seriously interfere with cyaniding and then result in the occurrence of "robbing gold effect the pretreatment of refractory gold ores, the bio-preoxidation has been developed rapidly because of its simple, mild and environmentally friendly processing conditions as well as low energy consumption. This paper analyses the causes and bio-preoxidation mechanism of carbonaceous matter in carbon gold deposits. However, the pretreatment of carbonaceous gold ore by bio-preoxidation is still in the research stage. Before the realization of its industrial application, some researches need to be done，such as developing different catalysts and building a new bacterial type which can oxidize not only arsenic sulfur and but also carbon. |
