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 Mines Mines Wildlife Management Area, a conservation area. The main industry is now farming. The name of this community derives from the discovery and mining of manganese here, beginning in the 1880s and ending in the 1890s. Also, Lafarge Canada operated a limestone quarry at Manganese Mines which closed in 1996. The limestone was used to produce cement. Manganese Mines Manganese Mines is an unincorporated community in Colchester County, Nova Scotia, Canada. This community is located about six miles north-east of Truro, between the South Branch North River and the Salmon River. The land was previously part of Onslow Township. It
