Manganese is a chemical element with Symbol "Mn" and atomic Number 25. It is a 12th most abundant element in the earth's crust, where it occurs as oxides and carbonates. The main manganese ores - pyrolusite, psilomelane, manganite, braunite and hausmannite - are all oxides. Pyrolusite (MnO2) is the most important . It is an iron-grey mineral with a metallic lustre, a hardness of 2 to 2.5 and a specific gravity of 4.8; Pyrolusite occurs as a pseudomorph of manganite or other manganese minerals, usually stratiform (arranged in layers) or reniform (kidney-like). Both open pit and underground methods are used to mine manganese ore, with open pit methods probably predominating.
The principal commercially important properties of Manganese are its ability to combine with and remove sulphur from iron, act as a deoxidiser, control the morphology of sulphides in steel to impart strength, toughness and hardness as an alloying element, act as depolarizer by suppressing the formation of hydrogen at carbon(+ve) electrodes in batteries.

High Purity Manganese Sulphate Monohydrate (HP MSM) :

Li-ion battery chemistries are using Manganese in their cathodes. HP MSM, generally having a 32% Mn content, a crystalline salt with very low impurity content is used to produce high quality Li-ion batteries like in NMC cathode chemistry. It is a high level rechargeable battery generally used in the automotive industry.
