中文摘要：
考察不同培养条件对生物淋滤溶出钴的影响,研究提高钴生物溶出效率的方法和工艺条件.研究表明：在硫磺质量浓度为4 g/L,起始pH为2.0,培养温度为27℃时,当电极混合材料的质量浓度为1%的条件下,淋滤12 d后钴的溶出质量浓度可达306 mg/L.降低淋滤体系起始酸度（pH为1.0）和改变淋滤液硫源组合（2 g/L硫磺和2 g/L黄铁矿）可以有效提高钴的生物溶出效率,淋滤12 d后钴的溶出质量浓度高达1 682 mg/L,溶出率超过90%.
英文摘要：
Influence of various conditions on the removal efficiency was investigated; especially the method to improve removal efficiency was studied. The results showed that when the concentration of sulfur was 4 g/L, the initial pH was 2.0, the culture temperature 27 ℃, the batteries dose 1%, and the released concentration of Co after 12 d bioleaching was 306 mg/L. Decrease in initial pH and change in S sources greatly improved the bioleaching of Co, the released concentration of Co was 1 682 mg/L and the removal efficiency over 90 % after 12 d.
