用坑道污水配制铀矿石堆浸淋浸剂的实践

USING PIT EFFLUENT TO MAKE LIXIVIANT FOR HEAP LEACHING OF URANIUM ORE

铀矿山坑道污水含有铀、镭、钍、钋等放射性核素,外排前必须加以处理。用坑道污水直接配制堆浸淋浸剂,不仅解决了污水处理问题,还提高了堆浸铀的提取率。

There are some radioactive nuclides such as uranium, radium, thorium and polonium in pit effluent of uranium mine. The effluent must be treated before discharging. Using pit effluent to make lixivant for heap leaching not only can solve the problem of effluent treatment, but also enhance the extraction rate of uranium.
