中文摘要: 对某砂岩型铀矿床的矿石进行了不同酸度和Fe3+浓度的微生物浸出试验,以及与酸法浸出(H2SO4浓度5 g/L)的对比试验。结果表明,微生物浸铀在4 g/L酸度、2 g/L Fe3+条件下铀浸出率最高(96.43%),比酸法浸出率高27%;微生物溶浸时Fe3+浓度超过2 g/L对浸铀没有明显的提升作用。
Abstract:One sand-type uranium deposit was bioleached with different acidities and Fe3 concentrations. The result was compared with that of acid leaching of 5 g/L H2SO4. The results show that the optimum bioleaching rate of uranium of 96.43% is obtained under the conditions of 4 g/L H2SO4 and 2 g/L Fe3 , which is 27% higher than that of acid leaching with 5 g/L H2SO4. Fe3 concentration over 2 g/L is not effective to promote uranium bioleaching.
