The results show that during bioleaching the chalcocite decom posed by two stages, the stageⅠis controlled by the concentration of ferric, with the increase of ferric concentration the oxidation rate of chalcocite is enhanced. The rate of stageⅡis slower than that of the stageⅠand it acts as the confining stage, and the concentration ratio of ferric to ferrous influences the oxidation rate at this stage.

计算与实验结果表明：模型仿真结果与实际结果较符合；堆浸过程次生硫化铜矿的氧化分为2个阶段，其中，辉铜矿反应步骤Ⅰ受溶液Fe3+浓度控制，随着Fe3+浓度增加，反应速率加快；反应步骤Ⅱ较反应步骤Ⅰ慢，为浸出反应的限制性步骤， Fe3+与Fe2+的浓度比是影响该反应步骤的关键因素。
