The mining of manganese ore was a very important economic activity in Arkansas between 1849 and 1959. The region around Batesville (Independence County)—including about 100 square miles loed in northwestern Independence County, southeastern Izard County, and northeastern Stone County—has produced more than ninetyeight percent of the manganese ore shipped from Arkansas. A second .
Assmang – Black Rock Mine Operations (BRMO) is one of two underground manganese ore mine operations in South Africa, mining both oxide and semicarbonate ores.. Mining operations began in 1940, at the Black Rock hillock, and subsequently expanded to the Nchwaning mines and Gloria mine in the Northern Cape.

more than 5 per cent of manganese is estimated at 50,000 tons, most of which is on the Bullion claim. The manganese oxides that form the ore bodies of this group were apparently deposited by solutions that followed fractures and seams in the rocks, but the source from which the solutions obtained the manganese is obscure.
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard brittle silvery metal, often found in minerals in combination with is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent, as a rubber ...
· 1. Introduction. Manganese oxides are critical environmental materials as powerful oxidants, as scavengers of important trace elements and reactive oxygen species, and as electron acceptors for anaerobic respiration (Myers and Nealson, 1988a, Tebo et al., 2005).Manganese is both the third most abundant transition metal in Earth's crust and has the largest number of oxidation .

Manganese ores can be carbonates, usually rhodochrosite but sometimes kutnahorite, or various silies and oxides, the most common being braunite, bixbyite, and hausmannite [see table of common minerals]. The carbonates carry useful isotope signals for C and O [see stable isotopes of Mn deposits]. On a purely descriptive basis, Mn ores can be ...
Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions. This would ensure much more consistent manganese content in the hot metal.
