摘　　要：对某铀矿山低品位铀矿石开展了不同矿浆浓度的细菌浸出摇瓶试验。在相同浸出条件下,经90h浸出,10%、20%、30%和40%矿浆浓度的铀浸出率分别为77.76%、76.20%、60.04%和35.85%,通过适度控制矿浆浓度可以维持比较好的铀浸出效率。Low grade uranium ore was bioleached in shake flask under different pulp concentration. Uranium leaching rate is 77.76%, 76.20%, 60.04%, and 35.85% respectively with pulp concentration of 10%, 20%, 30%, and 40% respectively after bioleached for 90 h under the same conditions. Reasonable leaching efficiency of uranium can be maintained by controlling appropriate pulp concentration.
