Uranium serves as the "grain" for the nuclear industry and constitutes a strategic resource essential for both national and energy security. Currently, the global uranium supply relies primarily on conventional extraction technologies, such as open-pit and underground mining combined with heap leaching, as well as in-situ leaching. These well-established technologies, characterized by high maturity and relatively low costs, represent the primary methods for uranium extraction at present. However, conventional uranium mining is facing mounting challenges, including the gradual depletion of high-grade resources and increasing difficulty in developing low-grade deposits. Therefore, it has become imperative to expand uranium extraction technologies toward unconventional resources. Unconventional uranium resource extraction technologies aim to recover uranium from low-grade polymetallic associated ores, seawater, and salt lake brines. Although various technical pathways are still in the research and development stage, they have demonstrated significant potential for broadening resource boundaries and achieving comprehensive resource utilization. This paper systematically reviews the fundamental principles, research progress, and future development trends of uranium extraction technologies, aiming to provide a reference for technological innovation and strategic direction in the field of uranium extraction.

铀作为核工业“粮食”，是保障国家安全和能源安全的战略性资源。目前，全球铀供应主要依赖常规提取技术，如露天和井下开采+堆浸、原地浸出等工艺。这些技术成熟度高、成本较低，是现阶段铀提取的主要方式。然而，随着优质资源逐渐枯竭、低品质资源开发难度不断加大，常规铀矿开采正面临多重挑战，推动铀提取技术向非常规资源领域拓展已成为必然选择。非常规铀资源提取技术主要面向低品位铀多金属共伴生矿、海水及盐湖卤水中的铀资源回收，技术路径多样。相关研究虽仍处于研发阶段，但在拓宽资源边界、实现资源综合利用方面已展现出重要潜力。系统梳理了铀提取技术的基本原理、研究进展与发展趋势，以期为铀提取领域的技术创新与方向选择提供参考。
