화학적으로 유사한 물질 분리 희토류 원소 악명 높을 정도로 어렵다. 주요 산업 방법 is solvent extraction, specifically liquid-liquid counter-current extraction. This process exploits subtle differences in the partition coefficients of rare-earth ions between an aqueous phase and an immiscible organic phase containing a complexing agent. By repeating the process over hundreds of stages, high-purity individual elements can be isolated.
