在难浸金矿石预处理的方法中细菌氧化工艺以其回收率高、生产成本低、无污染而已成为最具竞争力的工艺。但在实际生产中还没有得到大规模推广，其关键是对参加反应的双方──细菌和硫化物矿物复杂作用机理研究尚欠突破性进展。含金硫化物在细菌氧化过程中具有不同的行为。显然，仅对细菌及实验条件、工艺参数进行研究是远远不够的，必须确立细菌氧化过程中硫化物的研究主体地位，系统地开展细菌氧化作用中硫化物的矿物学研究已势在必行，它不仅具有理论指导意义而且具有加速工业化的现实意义。
In the refractory gold ore pretreatment method, the bacterial oxidation process has become the most competitive process with its high recovery rate, low production cost and no pollution. However, the actual production has not been large-scale promotion, the key is to participate in the reaction of both ─ ─ bacterial and sulfide minerals complex mechanism of action is still not yet breakthrough. Gold-containing sulfides have different behaviors during bacterial oxidation. Obviously, it is far from enough to study the bacteria, experimental conditions and process parameters only. Therefore, it is necessary to establish the dominant position of sulfide in the process of bacterial oxidation and systematically carry out the mineralogical study of sulfide in bacterial oxidation. , Which not only has theoretical significance but also has the practical significance of accelerating industrialization.
