| 摘 要： | 着重介绍原地爆破松动浸出采铀新工艺。东北某铀矿床爆破松动后矿石的渗透系数由0.08 m/d增加至0.4 m/d,增大了4倍。浸出时间58 d,试验区共注入溶浸剂214 m3,总抽液量191 m3,浸出液平均(ρU)407mg/L,浸出铀76.96 kg,浸出率71.7%。试验证明,原地爆破松动浸出是开采泥质矿石的一种技术较先进、经济效益好的新型采铀法。

| Abstract: | A new process is introduced,which is leaching of uranium after in-place blasting out.A test is carried out with this process at a uranium deposit of Northeast China.The test result shows that the ore permeability is increased from 0.08 m/d to 0.4 m/d after blasting out.The leach time is 58 d.The lixiviant injected into the test block is 214 m~3;the total pumped lixivium is 191 m~3;the average uranium concentration is 407 mg/L;the leached uranium is 76.96 kg;leaching rate is 71.7%.It has been proved that this new process is suited for mining muddy ore.It has better economic benfits. |
