Abstract
To provide a rare earth element recovery method that has a low environmental impact and can achieve rare earth element recovery at low cost and with high efficiency. A rare earth element recovery method includes: mixing a liquid containing a rare earth ion with torula yeast, thereby adsorbing the rare earth ion by the torula yeast under an acidic condition to obtain a mixed liquid; separating the torula yeast from the mixed liquid obtained in the adsorbing; and recovering the rare earth ion from the torula yeast separated in the separating.
