Manganese ore is silver-grey metal with a pinkish tinge. It is hard metallic element although it is quite brittle. Manganese ores are found in metamorphic rocks or sedimentary deposits. Pyrolusite is the main ore mineral for manganese. Manganese easily combines with air and water and is therefore a reactive element frequently found in the nodules on the sea floor. It is one of the 12 most abundant elements making up the Earth’s crust. Ukraine and South Africa holds over 80% of the word’s manganese ore reserves rest 20% Australia, Brazil, China, India, Gabon and Mexico. The U.S., Japan and Western Europe are all nearly deficient in economically mineable manganese. Manganese ore is alloyed with steel to improve hardness which is essential in the manufacturing of construction materials. It has a similar application when alloyed with aluminium and helps to reduce corrosion and is used in the manufacturing beverage cans. Manganese meal is used colorant in bricks and ceramics and is a catalyst and oxidizer. Manganese dioxide is used in dry cell batteries, in black paints to quicken dry time and to decolour and in the manufacture of ferroalloys. Manganese sulphate is used as a micronutrient in fertilizers and animal feeds. It is an important trace nutrient in animals and humans as it cofactors with enzymes and is a detoxification agent. It aids the body to absorbing vitamin B1 and makes bones strong and flexible. In the form of potassium permanganate it is used as a bactericide and algicide in water and waste water treatment.
