摘要
采用细菌渗滤浸出的方式，对比不同铀矿石粒径（2～5mm，5～10mm）对铀浸出和细菌适应性的影响。试验采用先酸浸后菌浸的方式。试验结果表明，细颗粒铀总浸出率与粗颗粒浸出基本相同；而粗颗粒总耗酸量小于细颗粒；细菌在粗颗粒铀矿样中的适应时间比在细颗粒铀矿样中的时间短，并且生长更为稳定。该试验可为在细菌浸出的条件下，为工业性生产增加铀矿石粒径节约生产成本提供试验依据。
The effect of leaching rate of uranium and the adaptability of bacteria with the different ore diameter （2～5 mm, 5～10 mm） using leakage-leaching are compared. The experiment uses the process of acid leaching and then bacterial leaching. The results show that the total leaching rate of minute diameter ore are always higher than the big diameter one, but for the quantum of consumed acid it＇s just an opposition. During bacterial leaching the adaptability of bacteria in big diameter ore are higher than in the minute one.
