Mining Significance
Terbium is a valuable heavy rare earth typically recovered in small quantities from mixed rare-earth deposits, including xenotime and some ion-adsorption clay systems. It is not generally mined independently. Its low abundance and demanding separation from adjacent lanthanides make recovery dependent on efficient beneficiation, leaching, and high-selectivity solvent-extraction circuits.
