Manganese ores are located in ore layers of 30-35 cm in the amount of 3-18 pieces and alternate with opoka (a type of carbonate-siliceous sedimentary rock [6]). Carbonate and oxidized layers are located in the upper part, and oxide ones in the lower part; in total, oxide ores – 26.5%, carbonate ores – 45.1%, oxidized – 15% and mixed ...
Organomanganese chemistry is the chemistry of organometallic compounds containing a carbon to manganese chemical bond.In a 2009 review, Cahiez et al. argued that as manganese is cheap and benign (only iron performs better in these aspects), organomanganese compounds have potential as chemical reagents, although currently they are not widely used as such despite extensive research.
