| Abstract: |
| The effect of column turning on column bioleaching rate of uranium was investigated with the ore collected from uranium ore heap leaching production line as raw materials. The results show that after 113 days of experiment, the leaching rates of liquid of uranium in two columns are 80.62% and 76.49% respectively, while the leaching rates of slag of uranium are 88.67% and 85.24% respectively, and acid consumption rates are 9.17% and 9.04% respectively. Column turning in the early stage of acidification can effectively reduce ore hardening and argillization and promote bioleaching of uranium. |
