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.

地浸采鈾先進(jìn)工藝 

2017年10月，中國(guó)首個(gè)千噸級(jí)綠色鈾礦示范基地——蒙其古爾原地浸出采鈾工程通過(guò)竣工驗(yàn)收。該鈾礦是中國(guó)首個(gè)特大型砂巖型鈾礦。為了推進(jìn)綠色發(fā)展，中核集團(tuán)鈾業(yè)公司按照探采一體化的要求，開(kāi)展了原地浸出開(kāi)采工藝的探索，并最終形成了“CO2+O2浸出法”先進(jìn)開(kāi)采工藝，使中國(guó)成為全球第二個(gè)掌握CO2+O2地浸采鈾技術(shù)和工業(yè)化應(yīng)用的國(guó)家。
