铀矿石的堆浸最初在葡萄牙应用。米勒等人确定了葡萄牙小而分散的铀矿床的铀矿石堆浸条件,按此条件生产已有七年之久。矿石含有0.5—5%的 FeS_2和0.1—0.3%的 U_3O_8,将其、破碎到25毫米,矿堆定期用水湿润。16个月内用这种方法提取了达80%的铀。美国发表了许多关于从含黄铁矿达10%的页岩堆浸铀的专利。在美国和加拿大对一系列矿床的铀矿石进行了铀的堆浸。对水和岩石的检验证明,其中存在硫堇菌-氧化铁硫杆
Heap leaching of uranium ore was originally applied in Portugal. Miller et al. Have identified the heap leaching conditions for uranium ore in small, scattered uranium deposits in Portugal and have been produced under these conditions for seven years. Ore contains 0.5-5% FeS_2 and 0.1-0.3% U_3O_8, crushing it to 25 mm, and the mine is periodically wetted with water. Uranium was extracted by this method up to 80% in 16 months. The United States has published many patents on heap leaching of uranium from shale containing up to 10% pyrite. Uranium heap leaching of a series of uranium deposits in the United States and Canada. Examination of water and rocks proved that there was a thionine-iron oxide sulfur rod in it
