Abstract
Provided is a method for separating lithium from a lithium solution containing lithium by 200 mg/L or more and fluorine by 20 mg/L or more, the method including: a first removal step of adding a first component, which solidifies the fluorine contained in the lithium solution, to the lithium solution and removing the fluorine solidified to obtain a F-removed liquid; and a second removal step of adding a second component, which solidifies the first component remaining in the F-removed liquid, to the F-removed liquid and removing the first component solidified to obtain a first component-removed liquid.
