摘要
细菌浸出作为一种经济、环保的处理技术,广泛应用于金属硫化物的金属提取和预处理过程中。为进一步理解细菌在硫化物浸出过程中的作用,详细阐述了细菌在浸出过程中的作用机理及其在矿物表面的作用机制,系统描述了金属硫化物溶解的硫代硫酸盐与多硫化合物途径。同时,还重点介绍了常见浸矿细菌的生存环境,并对不同种类浸矿细菌之间的协同作用进行了分析。
As an economic,environmental treatment technology,bioleaching is widely used in metal extraction and pretreatment of metal sulfide.In order to further understand role of bacteria during leaching of sulfide minerals,mechanism of bacterial action during leaching and on mineral surface are described in detail,and thiosulfate and polysulfide pathways of metal sulfide dissolution are also systematically described.In addition,common bacteria and their survival environment are introduced,and synergy between different kinds of bacteria is analyzed.
