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).

By Mike Ives • January 28, 2013. In November, the first shipment of raw "rare earth" minerals arrived at an $800 million processing plant on Malaysia's east coast near the home of Tan Bun Teet. The plant, run by Australia's Lynas Corporation, has since begun refining the rare earth metals, essential components in wind turbines, hybrid ...
Rare Earth Elements: The group of REEs in the study consisted of 16 elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Gd, Tb, Dy, Tm, Yb, Y, Sc). A key toxicological characteristic of the REEs is their common ability to displace calcium from calcium-binding sites in living systems, resulting in enzyme inhibition or other …
