Metal Ore

Manganese ore

Manganese (Mn) is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85% to 90% of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to provide most of this key ingredient to steelmaking. Products for construction, machinery, and transportation are leading end uses of manganese. Manganese also is a key component of certain widely used aluminum alloys and, in oxide form, dry cell batteries. As ore, additional quantities of manganese are used for such nonmetallurgical purposes as plant fertilizers, animal feed, and colorants for brick.

Concentrating the ore is the key to high Manganese content and consistent quality

Manganese overview

Manganese in alloy form is an essential input in steel making and is one of the most important metals in an industrial economy. Manganese ores of major commercial importance are (i) pyrolusite (MnO2, Mn 63.2%); (ii) psilomelane (manganese oxide, containing water and varying amounts of oxides of Ba, K and Na as impurities; Mn commonly 45-60%); (iii) manganite (Mn2O3. H2O, Mn 62.4%); and (iv) braunite (3Mn2O3, MnSiO3, Mn about 62% and SiO2 about 10%).
Our production consists of pyrolusite with an overburden consisting mainly of rhodochrosite, which is the red carbonated manganese mineral. We are the only producer in Turkey exporting manganese ore and concentrate suitable for EMD production.
