- Manganese Oxide (MnO) Manganese Sulfide (MnS) Potassium permanganate (KMnO 4) Interesting facts: It is an essential trace nutrient in all forms of life. Paints that were pigmented with manganese dioxide can be traced back 17,000 years. Manganese ore was first confused with magnetic iron ore. One source of manganese is in nodules on the ocean floor.
- Manganese (Mn) is a grey white metal that has the atomic number 25 in the periodic table. It is a Transition metal and located in Group 7 of the periodic table. It has the symbol Mn.
As in the case of titanium, vanadium, and chromium, the highest oxidation state (+7) of manganese corresponds to the total number of 3 d and 4 s electrons.

Manganese is a reactive, silvery-gray metal, with a pinkish tinge. Its principal use is in the manufacture of alloy steel. Manganese steels may have a high percentage of manganese (70-80% manganese, 20-30% iron). These materials are called ferromanganese.
The principal ore of manganese is pyrolusite, MnO2, which occurs in black, massive forms and as a fine black powder. The mineral manganite is an oxide with a hydroxyl group, MnO(OH). Another form of the oxide MnO2 is called ramsdellite . It also forms an oxide mineral of Mn3O4 called Hausmannite and Mn2O3 in the mineral Bixbyite. Manganese is found with iron and zinc in the oxide mineral Franklinite. An oxide of manganese with zinc is Hetaerolite. An oxide of manganese with tungsten and iron is Wolframite. Manganese forms an oxide mineral with titanium, iron and lead called senaite. Manganese forms an oxide mineral with barium and potassium called Hollandite. An oxide with tungsten is Hubnerite. Manganese forms an oxide along with magnesium and other metals in the mineral birnessite. An oxide formed along with barium is called romanechite. Manganese is found with zinc and iron in the mineral chalcophanite. It appears with niobium in the oxide mineral columbite and with niobium, tantalum and iron in manganocolumbite and manganotantalite. Manganese is part of the mineral zincite, a major ore of zinc.
Manganese is found in the red carbonate mineral rhodochrosite, MnCO3, which is sometimes of gem quality. Manganese appears in the carbonate mineral Benstonite.
The hydroxide mineral of manganese is called pyrochroite. Manganese sulfide, MnS, in mineral form is called alabandite.
Manganese is a constituent of a number of silicate minerals such as leucophoenicite, spessartine, Mn3Al2(SiO4)3 and serandite, Na(Mn,Ca)2 Si3O8(OH). Manganese appears with calcium, aluminum and boron in the borosilicate manganaxinite. Manganese appears with zirconium in the silicate eudialyte.
Manganese with boron forms the oxide sussexite. It also appears in bannisterite and bustamite. It appears with beryllium in the silicate helvite. Manganese appears with magnesium and arsenic in the silicate Ardennite. Manganese with magnesium, zinc and arsenic form the silicate mcgovernite.Manganese with calcium forms the mineral bustamite. Manganese with calcium and lead forms the mineral roeblingite. Manganese with zinc forms the silicate Hodgkinsonite. Manganese is found in the silicate mineral Langbanite along with antimony, iron and calcium. It appears with titanium in the mineral astrophyllite.
Manganese appears with titanium, arsenic and iron in the arsenate mineral cafarsite.
Manganese appears in the phosphate minerals Childrenite and Hureaulite. Another manganese and barium-containing phosphate is kulanite. Manganese, iron and magnesium form the phosphate mineral ludlamite. Graftonite is a phosphate mineral of iron, manganese and calcium. Strunzite is a phosphate mineral of iron and manganese. Zinc appears with manganese and iron in the phosphate mineral phosphophyllite.
Manganese dioxide is used as an oxidizing agent in ordinary dry cell batteries.
Potassium permanganate, KMnO4, is the most important compound of manganese. Crystallizing as deep red prisms, it dissolves in water to an intensely magenta colored solution. A powerful oxidizing agent, it is used as a disinfectant.

Manganese is a hard light grey color metal, often used in various alloys and known as the key element for electromagnetism. The name of this element is derived from Latin word meaning magnet. Manganese is essential for all living creatures and things as it is a part of a large number of enzymes. We consume manganese with food like nuts, parsley, tea, cereals, etc. This element is known as the fifth most abundant element on our planet, and it can be found on the surface of earth both in soils and in a large number of minerals (a big portion of such minerals in mined in Africa). Manganese can also be found in waters of oceans. This element is usually used in alloys with steel to produce super strong products like rails, prison bars, ruffles, safes, etc. Other common alloys of manganese used to industry are the ones with copper and aluminum.
Uses of Manganese
Manganese, silvery white, hard metallic element with the symbol Mn, is very important in steelmaking and in aluminum alloys. It is used in textile printing, paint, dry cell batteries, drink cans, and fertilizers. Manganese sulfate is used as a reducing agent in the manufacturing of paint and varnish dryers. Potassium permanganate is preferred as an antiseptic or disinfectant. Manganese dioxide is mainly used in dry cell batteries such as zinc-carbon batteries. This compound is also used as a pigment in ceramics and glassmaking. Manganese alloys are also used in organic chemistry, Portland cement mixtures and producing pink colored glass.
