The method includes: mixing the material with an aqueous sulfuric acid solution or water to prepare a mixed liquid; and mixing the mixed liquid with a slightly or sparingly soluble calcium-containing alkaline agent to form a precipitate containing fluorine and calcium, followed by solid-liquid separation to obtain a purified solution having lithium dissolved therein. In the preparation of the a mixed liquid, the material and the sulfuric acid aqueous solution or water are mixed and heated at 60° to 90° C.",
