Abstract

A method of the present invention includes: a dissolving step of mixing a compound containing lithium (Li) element and an aqueous liquid to obtain an aqueous lithium solution; a recovery step of recovering a solid component containing lithium (Li) element from the aqueous lithium solution; and a washing step of washing the solid component with an aqueous liquid. The washing step preferably includes n washing stages from a first washing step to an n-th washing step (where n is a natural number of 2 or greater). Also, a waste washing liquid generated in the first washing step is preferably used as the aqueous liquid to be mixed with the compound in the dissolving step. Also, a waste washing liquid generated in a p-th washing step is preferably used as the aqueous liquid to be mixed with the compound in the dissolving step or used to wash the solid component in a (p-m)-th washing step (where p is a natural number of from 2 to n; and m is a natural number of 1 or greater, and less than p).
