| Abstract: |
| Six columns after 120-day uranium bioleaching were water sprayed with different time intervals of washing heap to obtain optimum washing technological parameters. The results show that 10-day continuous water spraying for bioleaching heap tailings can significantly improve pH value. About 0.6% of uranium metal is leached with uranium concentration reduced to 10 mg/L in leaching solution. |
