| 摘 要： | 微生物浸出技术是处理低品位矿石的有效措施。阐述了目前我国有色金属矿产资源的紧缺局面,分析了我国现有低品位矿产资源现状,认为开展微生物浸出技术是提高我国矿产资源开发利用率、缓解我国资源短缺的重要途径。回顾了微生物浸出技术的发展历程,并叙述了该技术在国内外铜、金、钴等有色矿山的工业化应用情况,分析了生物浸出技术目前存在的主要问题,从浸矿微生物的选育和基础生物学、矿石-溶液-微生物作用机理、矿岩散体渗流特性及传质规律、微生物堆浸工艺学等角度总结了微生物浸出理论研究与发展趋势。

| Abstract: | Bioleaching technology is effective to treat low-grade ore.The shortage of mineral resources of non-ferrous metals and the actual situation of mineral resources with low grade in China are investigated.It is suggested that bioleaching technology could be an important approach to enhance the recovery of mineral resource and to alleviate the resource shortage in China.The development of bioleaching technology is reviewed,and its industrial application in copper,gold and cobalt mine at home and abroad is summa... |
