A method for producing a lithium-containing solution includes an adsorption step of bringing a lithium adsorbent obtained from lithium manganese oxide in contact with a low lithium-containing solution to obtain post-adsorption lithium manganese oxide, an eluting step of bringing the post-adsorption lithium manganese oxide in contact with an acid-containing solution to obtain an eluted solution, and a manganese oxidation step of oxidating manganese to obtain a lithium-containing solution with a suppressed manganese concentration. The adsorption step, the eluting step, and the manganese oxidation step are performed in this order, and the acid-containing solution includes the eluted solution with acid added.

    Abstract: A method for producing lithium hydroxide that allows reducing a load of removing divalent or more ions with an ion-exchange resin is provided. The method for producing lithium hydroxide includes steps (1) to (3) below. (1) a neutralization step: a step of adding an alkali to a first lithium chloride containing liquid to obtain a post-neutralization liquid, (2) an ion-exchange step: a step of bringing the post-neutralization liquid into contact with an ion-exchange resin to obtain a second lithium chloride containing liquid, and (3) a conversion step: a step of electrodialyzing the second lithium chloride containing liquid to obtain a lithium hydroxide containing liquid. Since this producing method allows roughly removing divalent or more ions in the neutralization step, a load of metal removal with the ion-exchange resin is reducible.
