| 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. |
