Influence of application of manganese ore in constructed …

 · Manganese (Mn) oxides are strong oxidants with high redox potential (Ding et al., 2015). As reported, Mn oxides actively participate in N-cycle in marine environments, thus, anoxic nitrification and denitrification are coupled to the reduction of Mn oxides and oxidation of Mn(II) under anoxic or anaerobic conditions ( Bartlett et al., 2008, Hulth et al., 2005, Hulth et al., 1999, Luther et al., 1997 ).

Manganese Steel

High manganese steel has a history dating back to the late 1800s. Initially know as Hadfield Steel after its inventor Sir Robert Hadfield who made the discovery of manganese steel, one of the first alloy steels, in 1882. Sir Robert Hadfield was a great believer in
