Minerals or Manganese Ore. Manganese ore is a silver-gray metal with a pinkish tinge. It is a hard metallic element although it is quite brittle. Read More
Among various types of manganese ores the largest accumulations of rich varieties occur in the supergene settings, in particular in laterite weathering crusts. This established empirical fact underlines the justice of the statement, made by V.I. Vernadskii in the beginning of the century that the highest concentrations of manganese were

2015-6-23 The Manganese deposits of Andhra Pradesh are associated with a thick sequence of Precambrian rocks, belonging to Khondalite and Charnockite groups of Dharwar Supergroup that forms part of 2500 to 3000 m.y. old Eastern Ghat complex of India. The study area is the Manganese deposits of Vizianagram-Visakhapatnam Manganese Belt of Andhra Pradesh.
Some varieties are isotropic and ot h- A comprehensive study of the manganese ore deposits of Banswara manganese belt (23°10′-23°20′N to 74°15′-74°25′E) in the Banswara district
The first data on the mineral composition and formation conditions of manganese ore at the Chapsordag and Malosyrsky deposits in the Askiz ore district of Khakassia are integrated and systematized. The detailed mineralogical mapping of the deposits has been carried out. The identification of minerals and examination of the ore microstructure were performed with optical microscopy in
a highly dispersed mineral substance consisting of MnO 2 ·n H 2 O and other hydroxides of manganese. It goes by various names, including earthy manganese and wad. Depending on the impurities it contains, bog manganese is divided into a number of varieties, including lampadite, containing CuO; tunnerite, containing ZnO; and asbolites, containing CoO + NiO.

More than 90% of the manganese ore mining worldwide goes to producing steel in the form of ferroalloys. What varieties are used? A variety of manganese products can give steel different properties: Ferromanganese is used as deoxidiser, desulphuriser and degasser of steel, to eliminate nitrogen and other hazardous elements that are found at the first melting of iron. It also improves mechanical
