摘要
叙述了生物浸出常用的多种硫杆菌的基本特征、金属硫化物细菌氧化机理、微生物浸矿的动力学研究方法及动力学模型,并探讨了生物冶金的发展方向。生物浸出利用特定微生物细菌对某些金属硫化物的氧化作用,使矿石中的金属离子溶解、富集,浸出率可达98%,堆浸萃取电解技术能从低品位矿石中把有价值的贵金属提取出来,取得较高的经济效益和广阔的市场前景。
The principal characteristics of various thiobacilli used in bioleaching, their catalysis, oxidation mechanism of metal sulfides, various kinetic models and formation methods are described in this paper. The future of bioleaching is discussed. Bioleaching technology distill valuable metal from mine ore by some special microorganism. The leaching index can be reached by 98%, Through this biotechnology, valuable precious metals can be extracted from the low grade, complicated and refractory ore and a wider marked foreground can be obtained.
