Field experiment of dilution-few reagent in-situ leaching uranium mining in the uranium deposit of Xinjiang

In order to avoid question of chemic precipitation which caused by high TDS in groundwater in weakly alkaline leaching,field experiment of dilution-few reagent in-situ leaching have been done based on studying in the laboratory.the results suggest that the dilution,oxygenation,acidification,increase reagent concentration are key technologies,and TDS of groundwater less than 4 g/L, dissolve Oxygen range from 250 to 350 mg/L,pH less than 6.9,HCO^-₃ range from 600 to 800 mg/L are optimal technology parameter.The technology will be a reference value on the similar situ leaching.
