Manganese is a chemical element with the symbol Mn and atomic number of 25. It is found as an oxide in nature (often in combination with iron) in many minerals, such as pyrolusite. [1] The free element is a metal with important industrial metal alloy uses. Manganese ions are variously colored, and are used industrially as pigments and as oxidation chemicals. Manganese (II) ions function as cofactors for a number of enzymes; the element is thus a required trace mineral for all known living organisms.

Pilbara Manganese, a subsidiary of Consmin, operates the Woodie Woodie manganese mine [4]
In 1932 Hanson wrote the book on Manganese deposits of Canada. [5]
The Kalahari Manganese Field (KMF) located in the Northern Cape of South Africa is a source of manganese. [14]
