PROBLEM TO BE SOLVED: To provide a production method that can obtain trimanganese tetraoxide by higher producibility than that of a conventional production method.SOLUTION: A production method of trimanganese tetraoxide in which the production of trimanganese tetraoxide is performed by crystallization from a manganese salt aqueous solution not through manganese hydroxide, includes a process in which the production of trimanganese tetraoxide is performed by crystallization in which a slurry density of a slurry containing trimanganese tetraoxide after crystallization reaction exceeds 1.13 g/cm. |
