| Abstract: |
| 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. |
