Advances in extraction techniques for rare earth elements from mineral ores

Abstract

Rare Earth Elements (REEs) are critical components in various high-tech industries due to their unique chemical and physical properties. The extraction of REEs from mineral ores presents significant technical challenges due to their low concentrations and the complexity of the ores. This review explores recent advances in extraction techniques for REEs, focusing on innovations in hydrometallurgical and pyrometallurgical processes, environmentally friendly extraction methods, and emerging technologies. The paper synthesizes current research findings, highlights the advantages and limitations of different techniques, and discusses future directions for improving the efficiency and sustainability of REE extraction.
