| Abstract: |
| Caused by high total dissolved solids (TDS) in groundwater in weakly alkaline in-situ leaching, chemical precipitation easily occurred in a uranium ore deposit. Field experiment of dilution-few reagent in-situ leaching was performed in laboratory. The results show that dilution, oxygenation, acidification, and cosolvent addition are the key technologies. The optimum parameters include TDS of groundwater of <4 g/L, dissolving oxygen concentration of 250~350 mg/L, pH<6.9, and HCO3- concentration of 600~800 mg/L. |
