| Abstract: |
| The bacterial leaching experiment was carried out for uranium ore under series connection conditions. The effects of series connection equipment and air inflation time on uranium leaching rate and acid consumption were analyzed. The results show that the average uranium leaching rates of three-barrels-series connection, two-barrels-series connection and single-barrel are 82.33%，81.42% and 83.62% respectively. The uranium leaching rate and acid consumption of the barrel rely on the latter are lower. Inflation can accelerate ion exchange speed and improve bacterial activity obviously. |
