Manganese Element information, properties and uses
Manganese is an extremely versatile element It can exist in six different oxidation states In nature, it is usually found in either its reduced +2 state, which easily dissolves in water or in the +4 state, which forms many types of insoluble oxides The +3 form of manganese is used as a powerful weapon, by dry rot fungi that break down wood2017年1月1日 In nature, manganese is concentrated in various manganese rocks of sedimentary and hydrothermalsedimentary genesis consisting predominantly (> 50%) of manganese minerals (Mn content—15–20% and greater); commonly this term is used in the literature as a synonym for manganese ore Manganese rocks by composition are Manganese Rocks and Ores ScienceDirect2019年12月3日 Manganese (Mn) oxide minerals influence the availability of organic carbon, nutrients and metals in the environment Oxidation of Mn(II) to Mn(III/IV) oxides is largely promoted by the direct and Mn oxide formation by phototrophs: Spatial and temporal Nature
