摘要
Abstract
The ore-bearing aquifer in a sandstone-type uranium deposit in Xinjiang has poor permeabili-ty and small amount of water in the well.When using the"CO2+O2"neutral leaching process,it is difficult to add oxygen,and the oxidation efficiency of U(Ⅳ)in the ore is low,resulting in a low leac-hing rate of uranium resources.To solve this problem,an efficient micro-nano oxygenation device was developed.The results show that this device can add oxygen steadily and continuously to the low per-meability and low water well.Under the condition that the leaching agent is supplemented with NH4HCO3 and the CO2 concentration is unchanged,compared with the traditional single well oxygen-ation,the concentration in the leaching solution increased by 35.95％,the oxidation capacity of the ore layer was increased,the oxygen consumption was reduced by 20.16％,and the monthly leaching rate was increased by 60.00％during micro-nano oxygenation.关键词
