| 摘 要： | 针对某硬岩铀矿品位低、浸出率不高、浸出时间长的特点, 采用驯化后的细菌进行了铀矿石原地破碎浸出现场试验。试验结果表明, 细菌浸出可以提高浸出液金属铀浓度, 降低硫酸消耗40%, 给企业带来好的经济效益, 具有良好的应用前景。

| Abstract: | Based on the characteristics of a hard-rock-type uranium mine such as low grade,low leaching rate and long leaching time,domesticated bacteria were introduced for in-situ bacterial stope leaching.The leaching tests show that the uranium concentration in leach solution climbs quickly,and the consumption of sulfuric acid can be reduced by around 40% with the bacterial leaching.As it will bring more economic benefits,this leaching technique has excellent application potential. |
