Manganese(II) oxide that the Mn ions form a face centered cubic magnetic sub-lattice where there are ferromagnetically coupled sheets that are anti-parallel with adjacent sheets. Manganese(II) oxide undergoes the chemical reactions typical of an ionic oxide. Upon treatment with acids, it converts to the corresponding manganese(II) salt and water. Oxidation of manganese(II) oxide gives manganese(III) oxide. MnO occurs in nature as the rare mineral manganosite. Commercially it is prepared by reduction of MnO with hydrogen, carbon monoxide or methane, e.g.: MnO can also be prepared by decarbonation of the carbonate: This calcining process is conducted anaerobically, lest MnO form.

Manganese, Minnesota Manganese, Minnesota Manganese was a small village in Wolford Township, Crow Wing County, Minnesota, United States. Manganese lies roughly north of Trommald, Minnesota. Just off County Road 30, it is perhaps best identified by its location between Coles Lake and Flynn Lake. First appearing in the 1920 census, the village was abandoned by 1960. Named after the mining of its namesake, the village first appeared as "Manganese Village" in the 1920 Census with a population of 183. A post office called Manganese was in operation from 1912 until 1924. Over time, like most other minerals in the Cuyuna Range, all
