METHOD FOR RECOVERING Li SALT |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method capable of recovering a Li salt at a high recovery rate efficiently from a Li resource such as brine water. <P>SOLUTION: In this method for recovering a Li salt including at least a step for concentrating Li<SP POS="POST">+</SP>by treating water containing Li<SP POS="POST">+</SP>by an ion exchange membrane electrodialyzer, the water is water having a heightened Li<SP POS="POST">+</SP>content rate by reducing monovalent ion other than Li by a solar crystallization method, and in the solar crystallization method, ions having high solubility are added in order to promote deposition of salts other than Li by operating phase equilibrium of the water. <P>COPYRIGHT: (C)2013,JPO&INPIT |
