Europium (Eu), one of the most significant rare earth (RE) elements, has wide applications as functional material in phosphor production, majorly used in fluorescent lamps, computer monitors, televisions etc. Eu is one of the three divalent lanthanides (along with Yb and Sm) having a reduction potential higher than −2 V. This possibility of Eu reduction is attributed to a relatively stable half-filled 4f⁷ electronic configuration, thus providing a high stabilization energy and selective recovery. But the Eu recuperation from natural minerals is either accompanied with other REs or Eu is recovered as a group of light REs. Selective recovery of Eu has sparked the progress for its reutilization through recycling of secondary resources. The perspectives of reclaiming Eu as a value added product from various sources using different pyro-hydro or hybrid techniques are discussed. The systematic research and salient findings on methods, viz., reduction, leaching, solvent extraction, as well as combined methods scaled-up to commercial scale to recover Eu, are also reported with recommendations. Thus, this comparative as well as summarized review hopes to help researchers to develop feasible processes for Eu recovery.

significant（Eu）是最重要的稀土（RE）元素之一，作为生产磷光体的功能材料具有广泛的用途，主要用于荧光灯，计算机显示器，电视等。Eu是三种二价镧系元素之一（与Yb和Sm）的还原电位高于-2V。Eu还原的这种可能性归因于相对稳定的半填充4f ⁷电子配置，因此提供了很高的稳定能量和选择性恢复能力。但是从天然矿物中回收的Eu可能与其他RE伴生，或者以轻稀土的形式被回收Eu。选择性回收of通过二次资源的回收激发了其再利用的进展。讨论了使用不同的焦氢或混合技术从各种来源回收Eu作为增值产品的观点。还报告了有关方法的系统研究和重要发现，即还原，浸出，溶剂萃取以及扩大到工业规模以回收Eu的组合方法。因此，这种比较性和总结性综述希望能帮助研究人员开发可行的Eu回收方法。
