摘要
首次开展利用地电化学法地浸采铀的实验室探索。不加任何试剂,利用含盐地下水为电解液,电解浸出矿石中的铀。初步研究了地磁场对地电化学法浸铀的影响。在地电化学法浸铀过程中由于浸出液中铀存在形式的特殊性,只依靠铀离子的电迁移还不足以使铀尽快地离开浸出区,电解液流动性对铀的浸出还有重要的影响。通过3个月的一维恒流试验,铀浸出率达到19.05%。实验室试验结果表明,地电化学法地浸采铀是可能的。
The lab study on the application of geoelectrical chemistry method in in-situ leaching of uranium is carried out. Uranium is leached from the ore with ground water containing salt (as electrolyte). The effect of geomagnetic field on leaching uranium with geoelectric chemistry method is studied. Because the state of uranium in leaching solution has special characteristics in the process of leach-ing uranium with this method, the leached uranium can not quickly flow off leaching field only depending on the electric migration of uranium ion. The flowability of electrolyte has important effect on leaching of uranium. The leaching efficiency of uranium reaches 19.05% through three months' one dimension constant discharge test. The test result has shown that it is possible using the geoelectric chemistry method in in-situ leaching of uranium.
