摘要: 利用自行设计的试验装置,采用从铀矿石样品中经富集分离、纯化、驯化诱变得到的氧化亚铁硫杆菌进行实验室浸铀试验。通过酸化与菌浸2个阶段4个样品的试验,使铀平均液计浸出率达到85.6%,渣计浸出率达到88.3%,浸出效果较为理想。

Abstract: Using self-designed test equipment, a lab test was made on the uranium leaching adopting Thiobacillus ferrooxidans (T.f )that was separated from uranium ore samples and then purified and domesticated. A two-staged test of acidification and leaching on four samples achieved an average uranium leaching rate of 85.6% by liquid and of 88.3% by slag, an relatively ideal leaching result.
