| Abstract: |
| The low grade uranium heap leaching tailing was column bioleached with different spraying intervals. The spray amount of three columns is 2% each time. The spraying is 6 h in duration with intervals of 18 h, 42 h, and 66 h respectively. The results show that uranium leaching rate is 87.83%, 77.23%, and 80.60% respectively after 300-day of spraying and 100-day of placement and washing. The uranium concentration in leaching solution is 50 mg/L above. |
