The "CO2+O2" neutral leaching uranium process is adopted for a sandstone uranium deposit in Xinjiang, there are mining areas with poor permeability and low water content of ore-bearing aquifers. In this kind of mining area, there are some problems in the single-hole oxygen adding mode, such as gas blocking, water returning from oxygen flowmeter, large maintenance workload and low oxygen solubility. Taking 5# mining area as an example, the study using micropore aeration oxygenation technology shows that the residual oxygen of single hole leachate increases by 226.85% on average, and the uranium concentration of leachate increases by 43.29% on average, the unit oxygen consumption per ton metal decreased by 30.77%, and the cost of developing oxygen facilities in mining area decreased by 96.09%. The technology of micropore aeration oxygenation technology solves the difficulty of oxygen addition in the process of "CO2+O2" neutral leaching, and provides a reference for oxygen addition in in-situ leaching of sandstone uranium ore.
