 · Spessartine is also a very typical constituent in metamorphic manganese ores and in Mnrich skarns where it occurs with other Mnsilies like pyroxmangite, rhodonite and pyroxenes. In both these environments near endmember compositions are quite common, but the individual crystals are quite small and not particularly well formed.

Abstract. This paper is concerned with three of the fairly common, manganese oxide minerals, manganite, hausmannite, and braunite. The study includes the precise determination of the minerals: (1) by Xray diffraction and (2) spectrographic analyses.

Manganese | Mn (Element)

Large quantities of manganese nodules are found on the ocean floor and may become a source of manganese. These nodules contain about 24% manganese, together with many other elements in lesser abundance. Most manganese today is obtained from ores found in Russia, Brazil, Australia, South Africa, Gabon, and India.
