The invention particularly relates to a method for recovering uranium from a uranium-molybdenum alloy, which comprises the following steps: performing high-temperature oxidation on the uranium-molybdenum alloy in a nitrogen atmosphere or an inert gas atmosphere, reacting uranium with oxygen to generate a triuranium octaoxide solid, and reacting molybdenum with oxygen to generate molybdenum trioxide gas, thereby realizing dry separation of uranium and molybdenum. According to the method for recycling uranium from the uranium-molybdenum alloy, uranium recycling through dry-method uranium-molybdenum separation is achieved, the uranium-molybdenum separation rate is high, the uranium recycling rate is high, the technological process is short, and less radioactive three wastes are generated. 本发明具体涉及一种铀钼合金中回收铀的方法，包括如下步骤：铀钼合金在氮气气氛或惰性气体气氛下进行高温氧化，铀与氧气反应生成八氧化三铀固体，钼与氧气反应生成三氧化钼气体，实现铀钼干法的分离。本发明的铀钼合金中回收铀的方法，实现干法铀钼分离回收铀，铀钼分离率高、铀回收率高、工艺流程短、放射性三废产生少。
