The ore-bearing aquifer in a sandstone-type uranium deposit in Xinjiang has poor permeability 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 leaching 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 permeability and low water well. Under the condition that the leaching agent is supplemented with NH4 HCO3 and the CO2 concentration is unchanged, compared with the traditional single well oxygenation, 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.

新疆某砂岩型铀矿床含矿含水层渗透性差,钻井运行水量小。采用“CO2+O2”中性浸出工艺时,氧气加入困难,矿层中的U(Ⅳ)氧化效率低,导致铀资源浸采率低。为解决该问题,研制了一种高效微纳米加氧装置。研究表明,该装置可为低渗透、低水量钻井稳定持续加入氧气。在浸出剂补加NH4 HCO3和CO2浓度不变的条件下,与传统单井加氧相比,采用微纳米加氧时,浸出液铀浓度提升了35.95%,增加了矿层的氧化能力,氧气单耗降低了20.16%,月度浸采率提升了60.00%。

新疆某砂岩型铀矿床含矿含水层渗透性差,钻井运行水量小。采用“CO2+O2”中性浸出工艺时,氧气加入困难,矿层中的U(Ⅳ)氧化效率低,导致铀资源浸采率低。为解决该问题,研制了一种高效微纳米加氧装置。研究表明,该装置可为低渗透、低水量钻井稳定持续加入氧气。在浸出剂补加NH4 HCO3和CO2浓度不变的条件下,与传统单井加氧相比,采用微纳米加氧时,浸出液铀浓度提升了35.95%,增加了矿层的氧化能力,氧气单耗降低了20.16%,月度浸采率提升了60.00%。

The ore-bearing aquifer in a sandstone-type uranium deposit in Xinjiang has poor permeability 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 leaching 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 permeability and low water well. Under the condition that the leaching agent is supplemented with NH4 HCO3 and the CO2 concentration is unchanged, compared with the traditional single well oxygenation, 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.
