Method for Extracting Lithium from Solution Containing Lithium |
| 摘要 |
Disclosed is a method of extracting lithium from a solution including lithium. The method of extracting lithium from a solution including lithium includes: separating the solution including lithium into a monovalent ion-containing solution and a solution including ions having more than divalence using a separation membrane having a negative charge on its surface; removing impurities from the monovalent ion-containing solution; and precipitating lithium dissolved in the monovalent ion-containing solution into lithium phosphate by adding a phosphorus-supplying material to the monovalent ion-containing solution. |

1. A method for extraction of lithium from a solution including lithium, comprising:
separating a solution including lithium into a monovalent ion-containing solution and a solution including ions having divalence or more using a separation membrane having a negative charge on its surface; removing impurities from the monovalent ion-containing solution; and adding a phosphorus supplying material to the monovalent ion-containing solution where impurities are removed and then precipitating dissolved lithium into lithium phosphate. |
