摘要
本文介绍了氧化亚铁硫杆菌经驯化后对淋浸铀矿条件的适应性。菌浸液多次循环氧化再生返回淋浸，获得浸出率大于９５％，节省用酸量３０％和省去软锰矿（ＭｎＯ２４０％）２．０％的结果。并探讨了细菌氧化再生液淋浸铀矿的基本原理、过程及若干影响因素，逆流淋浸方式，菌浸液氧化再生技术及氧化亚铁硫杆菌在提铀工艺过程中的其它技术问题。
This paper describes the adaptation of the domesticated thiobacillus ferrooxidans to the trickle leaching conditions of uranium ore. When the bacterial leaching liquor through multiple cyclesof oxidation and regeneration was used to return to the trickle leaching, the following resultswere obtained: the extraction rate was more than 95 %,the acid consumption was saved by 30%,and the consumed 2. 0% pyrolusite(MnO,40% )was eliminated. The following problems are discussed in the paper: the basic principle, process and some factors influencing the process Of thetrickle leaching of uranium ore using regenerated liquor of bacterial oxidation, counter--currenttrickle leaching mace,oxidation and regeneration techniques of bacterial ie..hi.g liquor and othertechnological problems on the process of uranium extraction by thiobacillus ferrooxidans.
