Guyuan 460 associated uranium molybdenum resources belong to amorphous colloidal sulfur molybdenum ore, which has the characteristics of complex mineral properties, difficult beneficiation and metallurgy, and long process flow. After more than 20 years of experimental research and production practice, a process development technology system of "oxygen pressure acid leaching modified filtration extraction separation process water cycle" has been formed. This article summarizes the technological innovation process of Guyuan 460 uranium molybdenum mine, which comprehensively innovates and practices from multiple aspects such as efficient leaching of uranium molybdenum ore, solid-liquid separation of slurry, separation and purification of uranium molybdenum, product preparation, process water recycling, key equipment and material engineering applications. Finally, an oxygen pressure leaching demonstration mine with an annual processing capacity of 200 000 tons of uranium molybdenum ore was built, greatly improving the scientific and technological level of complex associated uranium molybdenum resource development in China. It is a typical embodiment of new quality productivity in the mineral field.
