  • Immerse primary Mn ores in neutral solution, purify chemically, and manganese sulphate with high purity are obtained. Making use of the selective heating property of microwave, Mn3O4 powder can be prepared controllably. The best technology conditions were established through experiments. The samples are characterized by SEM, TEM, XRD and BET. The results show that using this method, high quality Mn3O4 can be prepared successfully from primary Mn ores with a high specific surface area of 28.27 m2/g.
