Abstract
A method for producing lithium manganese oxide that is a precursor of a lithium adsorbent under atmospheric pressure is provided. The method for producing a precursor of a lithium adsorbent comprises the following steps (1) to (3): (1) A 1mixing step of mixing a manganese salt and alkali hydroxide, so as to obtain a 1slurry containing manganese hydroxide; (2) a 2mixing step of adding lithium hydroxide to the 1slurry and then mixing the mixture to obtain a 2slurry; and (3) an oxidation step of adding an oxidizing agent to the 2slurry, so as to obtain a precursor of a lithium adsorbent. The method for producing a precursor of a lithium adsorbent comprises these steps, so that a precursor of a lithium adsorbent can be produced under atmospheric pressure. Therefore, a precursor of a lithium adsorbent can be produced at a limited cost.
