Advanced Technology of In-situ Leaching Uranium Mining
In October 2017, construction of China's first pilot kiloton-class green uranium mining operation – Mengqiguer in-situ leaching uranium mine – passed the final inspection. The areawhere the mine is located has an extra-large sandstone-type uranium deposit, the first of this kind found in China. In its push to green its operations, the China National Uranium Co., Ltd. has developed the "CO2+O2 leach" process based on extensive research on all aspects of in-situ leaching, and taking into consideration the need for integrating uranium exploration and mining. China became the second country in the world to use the CO2+O2 in-situ uranium leaching technology on an industrial scale.
地浸采铀先进工艺
2017年10月，中国首个千吨级绿色铀矿示范基地——蒙其古尔原地浸出采铀工程通过竣工验收。该铀矿是中国首个特大型砂岩型铀矿。为了推进绿色发展，中核集团铀业公司按照探采一体化的要求，开展了原地浸出开采工艺的探索，并最终形成了“CO2+O2浸出法”先进开采工艺，使中国成为全球第二个掌握CO2+O2地浸采铀技术和工业化应用的国家。
