The Properties and Effects of Manganese as an Alloying Element

The product is used as a reducing agent in the production of low-carbon ferromanganese. Medium- and low-carbon ferromanganese is a product of low carbon and silicon content is obtained by fusing manganese ore, coal, and lime flux in a furnace, thus forming a MnO-rich melt. This is later contacted with low-carbon silicomanganese or silicomanganese.

22.10: Chelating Agents - Chemistry LibreTexts

Nov 05, 2020· Contributors; Although we have confined our discussion so far to simple ligands such as Cl –, NH 3, or H 2 O, much larger and more complied molecules can also donate electron pairs to metal ions. An important and interesting example of this is the chelating agents—ligands which are able to form two or more coordinate covalent bonds with a metal ion.
