  • manganese Uses, Facts, & Compounds Britannica

    Manganese(II) oxide, or manganese monoxide (MnO), is used as a starting material for the production of manganous salts, as an additive in fertilizers, and as a reagent in textile printing. It occurs in nature as the green mineral manganosite. It also can be prepared commercially by heating manganese carbonate in the absence of air or by passing

  • Manganese, Chemical Element water, uses, elements,

    Manganese never occurs as a pure element in nature. It always combines with oxygen or other elements. The most common ores of manganese are pyrolusite, manganite, psilomelane, and rhodochrosite. Manganese is also found mixed with iron ores. The largest producers of manganese ore in the world are China, South Africa, the Ukraine, Brazil, Australia, Gabon, and Kazakstan.
