摘要
以内蒙古某铀矿山A、B、C采区为研究对象,从浸出液铀质量浓度、资源回收率及工艺井运行水量等方面研究了采区的浸出运行效果。在浸出运行周期内,3个采区的浸出率分别为96.01%、91.69%和82.55%,均高于75.00%的工业设计指标;研究结果验证了采用CO 2+O 2地浸采铀技术对该砂岩型铀资源进行工业开采的可靠性。
Taking three mining areas A,B and C of a uranium mine in Inner Mongolia as the research object,the leaching operation effect of the mining area is studied from the aspects of uranium concentration of leaching solution,resource recovery rate and operation water volume of process well.In the period of leaching operation,the leaching rates of the three mining areas are 96.01%,91.69%and 82.55%respectively,which are higher than the industrial design index of 75.00%,which verifies the reliability of CO 2+O 2 in-situ leaching technology for the industrial exploitation of sandstone type uranium resources.
