Abstract

The role of chloride ion in the performance of extreme thermophiles bacterium Sulfolobus acidocalarius in bioleaching process of copper sulfide concentrate at Midouk Shahr-e-Babak Complex was investigated. The gradual adaptation of bacteria to chloride ions at pH=1.5 showed that the presence of chloride ions in solution reduced the reproduction and growth rate of bacteria but did not prevent their growth. Results indicated that the effect of decreasing pH from 2.0 to 1.5 on bioleaching of copper sulfide concentrate is to increase the recovery of copper in the first few days, and nearly 100% of copper was extracted after 9 d. As the solid content in solution increases from 1% to 3%, about more 6 d was required to extract copper. Bioleaching of copper sulfide concentrate revealed that the dissolution of copper sulfide concentrates at constant pH=1.5, 1% solid content, and concentration of 0.5 mol/L and 1.0 mol/L NaCl after 9 d, was 98% and 80%, respectively; and after 21 d, it reached nearly 100% and 90%, respectively. Under the same conditions without microorganisms, copper extraction reached 62%. The kinetics of bioleaching and leaching is a combination of diffusion and chemical reaction.

摘要

本文研究了在生物浸出Midouk Shahrr-e-Babak 铜矿复合体系中, 氯离子对用极端嗜热菌Sulfolobus acidocalarius 生物浸出硫化铜精矿的影响。细菌在pH=1.5 时逐渐适应氯离子, 说明溶液中氯离子的存在只是降低了细菌的繁殖和生长速度, 但并没有阻止细菌的生长。当pH 从2.0 降低到1.5 时, 在前几天铜的浸出率逐步提高, 9 d 后铜的浸出率接近100%。随着溶液中固体含量从1% 增加到3%, 铜浸出时间延长了6 d。在pH=1.5、固体含量为1%、NaCl 浓度为0.5 mol/L 和1.0 mol/L 的条件下, 9 d后的浸出率分别为98% 和80%; 21 d 后, 浸出率分别达到近100% 和90%。在无微生物但其他条件相同的情况下, 铜的浸出率仅为62%。
