| 摘 要： | 以某难处理铀矿石为原料,开展了不同细菌接种量对铀生物浸出的影响研究。在相同浸出条件下,经84h浸出,5%、10%、20%和30%细菌接种量的铀浸出率分别为50.46%、56.42%、62.38%和67.05%,细菌接种量越大,铀浸出率也越高。在铀矿生物浸出工艺中,可以通过控制细菌接种量来获得适宜的浸铀效率。

| Abstract: | Effects of inoculation amount of bacteria on uranium bioleaching were studied applying one refractory uranium ore as raw material. Under the same leaching condition, uranium leaching rates for 5%, 10%, 20%, and 30% bacterial inoculation after inoculation at 84 h is 50.46%, 56.42%, 62.38% and 67.05%, respectively. The higher the inoculation rate is, the higher the leaching rate of uranium is. Proper uranium bioleaching rate can be obtained by controlling amount of bacteria inoculated in refractory uranium bioleaching process. |

| Keywords: | low grade uranium ore bacterial inoculation ratio bioleaching |
