| 摘 要： | 以某难处理铀矿石为原料,开展了添加不同浓度Fe~(2+)对铀生物浸出的影响研究。在相同浸出条件下,经84h浸出,添加Fe~(2+)浓度为0、3、5、9g/L的铀浸出率分别为48.13%、61.44%、66.12%和62.38%,添加Fe~(2+)浓度为5g/L时,铀浸出率最高。可以通过控制添加适当Fe~(2+)浓度来获得较高的铀浸出率。

| Abstract: | Effects of addition of different Fe2+ concentrations on uranium leaching were studied with refractory uranium ore as raw materials. Under the same leaching conditions and leaching period of 84 h, uranium leaching rates are 48.13%, 61.44%, 66.12% and 62.38% respectively with Fe2+ addition of 0, 3, 5 and 9 g/L. The highest uranium leaching rate is obtained with Fe2+ concentration of 5 g/L. Higher leaching rate of uranium can be obtained by controlling addition of appropriate Fe2+. |

| Keywords: | Low grade uranium ore bioleaching Fe2+ concentration uranium leaching rate |
