摘要
针对CO_(2)+O_(2)原地浸出采铀过程,通过对氧气溶解机制、氧气喷射混合、氧气静态混合及钻孔氧气溶解情况等因素的分析,提出了一种适用于低流量钻孔的O_(2)加注方式,实现了低流量钻孔的O_(2)加注,提高了低流量钻孔浸采单元浸出效果,缩短了浸出周期,提高了资源回收率,降低了浸采成本。
Aiming at the process of uranium mining by carbon dioxide and oxygen in-situ leaching,through the analysis of factors such as oxygen dissolution mechanism,oxygen jet mixing,oxygen static mixing and oxygen dissolution in borehole,an oxygen injection method suitable for low flow borehole is proposed,which realizes the oxygen injection of low flow borehole,improves the leaching effect of low flow borehole leaching unit,shortens the leaching cycle and improves the resource recovery and the leaching cost is reduced.
