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
Montezuma Mining Company Ltd: The Butcherbird Manganese project is located 120 km south of Newman. A scoping study was conducted into the development of a mine with capacity to produce up to 1 Mtpa with a mine life of at least 10 years. The study showed excellent potential for the commercial development of the Butcherbird manganese project.
In 2012, BHP Billiton began developing a second manganese deposit. Iron ore was discovered as early as 1895, but the first commercial mining lnse for iron ore was only issued in 1955. Manganese Mining in Gabon. Currently, Gabon manganese reserves are estimated to be around 250 million tons with a metal content of between 48% and 52%.

The mineral composition of manganese-bearing minerals is dependent on how the nodules are formed; sedimentary nodules, which have a lower Mn 2+ content than diagenetic, are dominated by Fe-vernadite, Mn-feroxyhyte, and asbolane-buserite while diagenetic nodules are dominated by buserite I, birnessite, todorokite, and asbolane-buserite. The growth types termed diagenetic and hydrogenetic
