摘要: 基于溶浸采铀技术、硬岩铀矿石的性质及表面活性剂功能,研究了表面活性剂在硬岩铀矿石浸出中应用的可能性。选用P1和P2 2种表面活性剂进行了铀矿石的搅拌浸出试验,结果表明:①表面活性剂P1在临界胶束浓度范围内(0.2~10 mg/L)可显著提高铀矿石的浸出率;②表面活性剂P2在临界胶束浓度范围内(50~150 mg/L)亦可明显提高铀矿石的浸出率;③表面活性剂P1提高铀矿石浸出率的效果比表面活性剂P2提高铀矿石浸出率的效果要明显;④表面活性剂可显著改善大块度铀矿石的浸出率。

Abstract: Based on uranium in-situ leaching mining technology, properties of hard-rock type uranium ore and surfactant functions, the possibility of applying surfactant in in-situ leaching of hard rock-type uranium ore was studied. Two surfactants, P1 and P2, were used in the test of agitated leaching of uranium ore. The results indicate that ①surfactant P1 can evidently improve the uranium leaching yield within the critical micelle concentration range (0.2-10mg/L);②surfactant P2 can also remarkably improve the uranium leaching rate within the critical micelle concentration range (50-150mg/L);③surfactant P1 has a better effect in improving the uranium leaching rate than that by surfactant P2; ④surfactant can remarkably improve the leaching rate of large sized uranium ore.
