Abstract

Provided is a method for manufacturing a granulated body for lithium adsorption with which it is possible to sufficiently suppress elution of manganese in an elution step in production of lithium on a commercial basis.　This method for manufacturing a granulated body for lithium adsorption comprises: a step for kneading a powder of a precursor of a lithium adsorbent and a binder to obtain a kneaded product; a granulating step for molding the kneaded product to obtain a first granulated body; and a sintering step for sintering the first granulated body to obtain a second granulated body. This configuration makes it possible to change the valence of manganese included in the precursor of the lithium adsorbent from 2 to 4, thereby suppressing elution of manganese in the elution step. This configuration also makes it possible to repeatedly use the lithium adsorbent in the production on a commercial basis. In addition, since the concentration of manganese in an eluent obtained in the elution step can be made low, the load in steps after the elution step can be reduced.
