摘要
总结细菌浸矿间接作用的研究成果,阐述细菌浸出过程间接作用的观点,从细菌间接作用角度较系统地分析细菌间接作用过程机理,说明间接作用过程的基本步骤。根据硫化矿物晶体结构不同,间接作用过程中,硫化矿的氧化分解有以S_2O_3^(2-)为中间过程和以Sn^(2-)与S_8为中间过程的两种氧化机理。
The achievements for indirect effect research of sulfide ores bio-leaching are summarized. The view of indirect effect mechanism of bioleaching is explained systematically, and the main process of bioleaching is illustrated. According to the structure of different sulfide, there are two different mechanisms with formation of the thiosulfate and polysulfide as intermediate process.
