Abstract

The article discusses wall rock neutralization acidin-situ leaching of uranium testing and pollution of groundwater purification combined with the natural purification of the indoor simulation tests. Test showed that the acidic groundwater can be neutralized by wall rock and the uranium can be also adsorbed. First £¬ the uranium of contaminated groundwater be recovered by ion exchange, Second, regulated pH of wastewater to 7 around using neutralize, Thirdly £¬ adsorbed by the Sand with clay, low grade uranium ore and tailings of lixiviated, the method is advanced which treatment groundwater of acid in-situleaching of uranium using surface treatment and self purification, for acid in-situ leaching of uranium to provide a reference.

酸地浸铀地下水处理技术研究:地表水处理与自然净化相结合
本文讨论了围岩中和酸浸铀矿试验和地下水污染净化结合室内自然净化模拟试验。试验表明,围岩对酸性地下水有中和作用,对铀也有吸附作用。首先采用离子交换法回收污染地下水中的铀,其次采用中和法将废水pH调节到7左右,第三采用粘土、低品位铀矿石和浸出的尾矿对砂进行吸附,提出了采用表面处理和自净化处理酸地浸铀地下水的方法,为酸地浸铀提供参考。
