Abstract

The article discusses wall rock neutralization acid-in-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-situ leaching of uranium using surface treatment and self purification, for acid in-situ leaching of uranium to provide a reference.
