中国铀资源采冶技术发展现状与展望OA

Over the past few decades,China's uranium resource mining and metallurgy technology has undergone a development process from nothing to something,and from weak to strong.It has intro-duced trackless mining and"three-under"mining technologies,broken through surface heap leaching and underground heap leaching,innovated in-situ blasting leaching and bacterial heap leaching,prac-ticed acid,alkaline and neutral in-situ leaching of uranium mining technologies,explored and im-proved borehole drilling,underground leaching methods and hydrometallurgical processes,built digit-al mines in Xinjiang and Inner Mongolia,verified the control of leaching area,the treatment and reuse of waste drilling mud,reverse osmosis treatment of waste liquids,and the groundwater remediation of decommissioned test mines,and implemented the rational mining and metallurgy of uranium-molybde-num and uranium-coal deposits,and explored the technology of extracting uranium from seawater.The new technologies and processes practiced in uranium resource mining and metallurgy have become the driving force for China's natural uranium production.Looking to the future,China's uranium re-source mining and metallurgy industry is bound to innovate and create greater breakthroughs.
