摘要: 对某铀矿山低品位铀矿石中铀资源进行了细菌浸出回收可行性试验研究。试验结果表明,铀品位为0.024 5%的低品位铀矿石中60%的铀能从中提取出来,酸耗小于4%,浸铀周期为70 d,表明应用细菌对该矿山低品位铀矿石的浸出具有一定的可行性。

Abstract: The feasibility of bacterial recovery of uranium from the lower grade uranium ores was studied.The experiment results showed that above 60% uranium can be extracted from the uranium mine's low grade waste ores which grade is 0.0245%, the acid consumption of bacteria column leaching is less than 4%, the leaching periods are about 70 d.It is indicated that application of the bacteria for leaching recovery of uranium from low grade uranium mine is feasible.  

Key words: Lower grade, Uranium ores, Column leaching, Bioleaching
