Following extraction, the REEs ores often undergo leaching processes to further refine and isolate the rare earth metals. This involves dissolving the ores in a suitable leaching agent before extracting the rare earth metals using methods such as precipitation, fractional crystallisation, and chromatography (Shahbaz, 2022).
