Method for Separating and Recovering Rare-Earth Elements |
| 摘要 |
A method for separating and recovering a plurality of rare-earth elements, the method including a step of introducing, into a liquid, a mixture containing a rare-earth oxychloride and a rare-earth chloride, the rare-earth oxychloride constituted from a rare-earth element different from a rare-earth element constituting the rare-earth chloride, thereby obtaining an insoluble matter containing the rare-earth oxychloride and a liquid in which the rare-earth chloride is dissolved, a step of recovering the rare-earth oxychloride from the insoluble matter, and a step of recovering the rare-earth chloride from the liquid in which the rare-earth chloride is dissolved. |

1. A method for separating and recovering a plurality of rare-earth elements, the method comprising the steps of:
introducing, into a liquid, a mixture containing a rare-earth oxychloride and a rare-earth chloride, the rare-earth oxychloride constituted from a rare-earth element different from a rare-earth element constituting the rare-earth chloride, thereby obtaining an insoluble matter containing the rare-earth oxychloride and a liquid in which the rare-earth chloride is dissolved; recovering the rare-earth oxychloride from the insoluble matter; and recovering the rare-earth chloride from the liquid in which the rare-earth chloride is dissolved. |
