Manganese dioxide is used in drying black paints and in the preparation of oxygen and chlorine. It also acts as a catalyst in the production of artificial flavors like vanilla and as an oxidizing agent in treating uranium ore to produce the oxide concentrate. Manganese compounds have also been used in the coloring of ceramics and glass.

sedimentary bodies of manganese ores in the Sausar of Balaghat district, Madhya Pradesh exhibit a definite trend in the formation and transformation of manganese oxide phases with progressive metamorphism. A regional trend is clearly noticeable from the paragenesis of Ore minerals in the manganese ore bodies from different metamorphic zones.
Manganese bearing rocks and ores were formed during the whole period of the Earths shell formation . Mn bearing and manganese rocks are known in the lithosphere since the Archean. They are typical of Proterozoic rocks. Such rocks occur at many Phanerozoic geo stratigraphic levels .
Manganese ore deposits are common in the Falang Formation of Ladinian age , southeastern Yunan, China. The deposits containing manganese oxide and manganese carbonate ores are not metamorphic in origin and they commonly contain bioclasts. Concentric ring structures are clearly observed in oolitic and pisolitic manganese ores.
It was discovered 1774 by Johann Gahn. Manganese easily reacts with water and air. On Earth, manganese is never found as a free metal, but it is found in a number of minerals. The most important of these minerals is pyrolusite, the main ore mineral for manganese. Manganese is essential to iron and steel production.
