Waste Water Treatment of CO2 + O2 in-situ Leaching Uranium
An in-situ leaching uranium mine locates in Northern China. The mine applies processes of CO2 + O2 leaching uranium of ore-bearing aquifer, The mine reduces consumption of the industrial reagent and water and generation and discharge of waste water as much as possible by comprehensive waste water treatment technology with process water recycle, reverse osmosis and natural evaporation. Process water of the mine that can be recycled and reused include barren fluid, solution washing loaded resin, solution regenerating barren resin, precipitating mother solution and filtered liquor of yellow cake.
