When it comes to natural mineral deposits, Nigeria is one of the top African countries that is richly blessed and with most of the mineral deposit yet untapped.
Manganese is deposited in the following states in Nigeria; Bauchi, Cross River, Benue, Borno, Adamawa, Kaduna, Kebbi, Katsina, Plateau, and Nasarawa.
Manganese is the 12th most abundant elements on earth crust; it has a symbol of Mn, atomic number of 25, the melting point of 1,246°C and a boiling point of 2,061°C.
It is a metal with a silvery-grey colour like that of an iron, it’s brittle, hard, tarnishes slowly in air and oxidizes.
Manganese minerals do not occur freely in nature and most times consists of oxides, silicates, and carbonates, minerals with manganese ore includes pyrolusite (MnO2), braunite (Mn2+Mn3+6)(SiO12), psilomelane (Ba,H2O)2Mn5O10, and rhodochrosite (MnCO3).
The demand of Manganese in Nigeria is on the increasing side as it is mostly used in the steel industries because of its physical and chemical properties, and there are also numerous local and international companies in Nigeria that are engaged in the commercial mining of Manganese which is exported to other African countries and beyond.

Uses of Manganese
- Due to its brittle nature, it is used as alloys in stainless steels.
- It’s also used in dry cell batteries.
- Drinks cans are made of an alloy of aluminium with 1.5% manganese, to improve resistance to corrosion.
- It forms highly magnetic alloys with aluminium, antimony, and copper.
- Manganese (IV) oxide is used as a catalyst, a rubber additive and to decolourise glass that is coloured green by iron impurities.
