摘　　要：难处理金矿在我国黄金资源中占据较大的比例,常规处理原生矿的方法焙烧法与加压氧化法因成本太高,不适合处理该低品位金矿。因此,采取细菌预氧化-氰化提金工艺试验进行研究分析。试验研究表明,最终金浸出率58·8%,试验指标较为理想。Refractory gold ores account for a large proportion of China＇s gold resources. The conventional roasting and pressure oxidation method to process the primary ores are not suited to deal with the low - grade gold mine because of the higher production costs . Therefore, the paper made a test to put the Bacterial Pre - oxidation - Cyanide Leaching approach into the production of gold . The experiment showed that 58.8% of the final gold leaching rate can be taken as an ideal indicator.
