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。
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+.
