Manganese - Wikipedia

Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. First isolated in 1774, manganese is mainly used in the production of steel. It is familiar in the laboratory in the form of the deep violet salt potassium permanganate. It occurs at the active sites in some enzymes

A Case Study ofthe Production ofHigh-grade Manganese ...

ficiating manganese ores by means of an agglomeration process were started in the 1970's. These investigations resulted in Ihe erection of a 500 ktla sinter plant at Samancor's Mamatwan manganese mjne in 1987. This plant initially produced a 44 per cent manganese sinter from a feed of 38 per cent carbonaceous manganese are.

Production of Ferro- Manganese – IspatGuru

19-06-2018  Ferro-manganese (Fe-Mn) is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron (Fe) and manganese (Mn) with a minimum Mn content of 65 %, and maximum Mn content of 95 %. It is produced by heating a mixture of the oxides of Mn (MnO2) and iron (Fe2O3) with carbon (C) normally as coke or coal.
