Manganese oxide is available in 20 different types and is categorized under the various categories of manganese in its oxidation state. Some of the categories of manganese are available in the mineral as:

  • Tetravalent (Mn+)
  • Trivalent (MnJ+)
  • Divalent (Mn2~) manganese oxides

The tetra and trivalent manganese oxides are available widely in the continental and marine environments, with a large percentage in the ocean floors.

Manganese oxide is a prime source of manganese for which it is used in the manufacturing of steel and in cathodic material in dry-cell batteries. Manganese oxide is further processed and is known as MnO slug. Some of the salient features of our high quality manganese oxide slug comprises of the following:
