    New Insight Into The Origin Of Manganese Oxide Ore

    Industrial manganese ores vary significantly in chemistry and mineralogy. It is well-known that the properties of a manganese ore have a large influence on the technology and efficiency of the production of manganese alloys. The melting and reduction behaviour of ores are defined by their chemistry, mineralogy and physical.

    INTRODUCTIONManganese is a strategically important metal that has several industrial uses. The most important are in the manufacture of steel, some non-ferrous alloys, carbon-zinc batteries and some chemical reagents.Manganese ore, present in the form of Pyrolusite (MnO 2 ), occurs at various localities in Egypt with reserves amounting than 401 million tons.

    Oct 16, 2016 Origin This manganese deposits formed by weathering of basement rocks rich in manganese as a source of the ore which deposited in fissures and cracks with some replacement along fracture walls (El Shazly,1957). The ore is a very low-temperature epithermal fissure deposit of black calcite type that occurs near the surface (oxidation zone) in brecciated zones along faults. An epigenetic low temperature origin was proposed based on the predominance of stable higher oxides of manganese and the.
