Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for recovering manganese which can obtain a leachate in which manganese is sufficiently leached and also iron is hardly leached from a raw material such as manganese ore including a manganese compound and iron. SOLUTION: A raw material comprising a manganese compound and iron is dissolved into a sulfuric acid aqueous solution, sulfuric acid is further added to the aqueous solution, while retaining its pH to
