【摘要】 以广西靖西县湖润锰矿床为研究基础,考查了矿床的基本地质特征,简要分析了矿床的成因。为了了解近地表氧化锰矿的形成机理,利用从该矿矿坑水中分离出的两种锰的氧化细菌(MetallogeniumSymbioticum和HyphomicrobiumVulgare)进行了一些锰的氧化实验。实验结果表明这两种细菌对锰具有明显的氧化作用,结合矿床的其他方面特征,认为自然界中微生物在锰的氧化富集过程中起着积极的作用,作用表现在两个方面:一方面微生物可以直接对锰进行氧化,使原生碳酸锰矿转变为氧化锰矿;另一方面微生物又可以改变环境的pH值,促进锰的化学氧化。更多还原

【Abstract】 The geological features of Hurun manganese ore deposit are studied in this paper. Then some experiments are carried out with two kinds of manganese-oxidizing bacteria,Metallogenium Symbioticum and Hyphomicrobium Vulgare, which are isolated from Hurun ore deposit. The results of experiments show that the two bacteria can oxidize manganese actually. Integrated with other features of the deposit, it is thought that microorganism plays an important role in the natural oxidization enrichment process of manganese.更多还原
