Lithium recovery method |
| abstract |
Provided is a lithium recovery method capable of recovering lithium with high purity from a liquid to be treated in which lithium and inorganic salts are dissolved. The lithium recovery method includes a concentration step (S8) of evaporating and concentrating the liquid to be treated in which lithium and inorganic salts are at least dissolved, and a crystallization step (S9) of cooling and crystallizing the liquid to be treated after the concentration step (S8) to precipitate inorganic salts as crystals (S9). ), a solid-liquid separation step (S10) of separating a precipitate containing inorganic salt crystals from the target liquid after the crystallization step (S9), and mixing carbon dioxide into the target liquid after the solid-liquid separation step (S10) and/or It has a carbonation process (S11) of adding a water-soluble carbonate, and a solid-liquid separation process (S12) of separating a precipitate containing crystals of lithium carbonate precipitated in the carbonation process (S11) from a liquid to be treated. |
