In an era of environmental degradation, and water, and mineral scarcity, enhancing microbial function in sustainable mining has become a prerequisite for the future of the green economy. In recent years, the extensive use of rare earth elements (REEs) in green and smart technologies has led to an increase in the focus on recovery and separation of REEs from ore matrices. However, the recovery of REEs using traditional methods is complex and energy intensive, leading to the requirement to develop processes which are more economically feasible and environmentally friendly. The use of phosphate solubilizing microorganisms for bioleaching of REEs provides a biotechnical approach for the recovery of REEs from primary and secondary sources. However, managing and understanding the microbial-mineral interactions in order to develop a successful method for bioleaching of REEs still remains a major challenge. This review focuses on the use of microbes for the bioleaching of REEs and highlights the importance of genomic studies in order to narrow down potential microorganisms for the optimal extraction of REEs.
在环境恶化、水资源短缺和矿产资源稀缺的时代，提高可持续采矿中的微生物功能已成为绿色经济未来的前提。近年来，绿色和智能技术中广泛使用稀土元素（REEs），这使得人们越来越关注从矿石基质中回收和分离 REEs。然而，传统方法回收 REEs 复杂且能源密集，因此需要开发更具经济可行性和环境友好性的工艺。利用溶磷微生物进行 REEs 的生物浸出为从原生和次生资源中回收 REEs 提供了生物技术方法。然而，为了开发成功的 REEs 生物浸出方法，管理和理解微生物-矿物相互作用仍然是一个主要挑战。本综述重点介绍了微生物在 REEs 生物浸出中的应用，并强调了基因组研究的重要性，以便缩小潜在微生物的范围，从而实现 REEs 的最佳提取。
