  • Manganese is a chemical element, designated by the symbol Mn.
  • It has the atomic number 25. It is found as a free element in nature and in many minerals.
  • Manganese is a gray-white metal, resembling iron.
  • It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized.
  • Manganese metal and its common ions are paramagnetic.
  • Manganese 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 metal is ferromagnetic only after special treatment. The pure metal exists in four allotropic forms. The alpha form is stable at ordinary temperature; gamma manganese, which changes to alpha at ordinary temperatures, is said to be flexible, soft, easily cut, and capable of being bent.
  • Manganese has played a key role in the development of various steelmaking processes and its continuing importance is indicated by the fact
    that about 90% of all manganese consumed annually goes into steel as an alloying element.
  • Manganese is a key component of low-cost stainless steel formulations and certain widely used alumimum alloys.
  • Manganese dioxide is also used as a catalyst.
  • Manganese is used to decolorize glass and make violet coloured glass. Potassium permanganate is a potent oxidizer and used as a disinfectant.
  • Other compound that find application are Manganese oxide (MnO) and manganese carbonate (MnCO3): the first goes into fertilizers and ceramics, the second is the starting material for making other manganese compounds.
  • Manganese is found widely in nature, but occurs only in trace amounts in human tissues.
  • In the human body, manganese functions as an enzyme activator and as a component of metalloenzymes.
  • Manganese activates the enzymes responsible for the utilization of several key nutrients including biotin, thiamin, ascorbic acid, and choline.
  • The human body contains a total of 15-20 milligrams of manganese, most of which is located in the bones, with the remainder found in the kidneys, liver, pancreas, pituitary glands, and adrenal glands.
  • Total world production of manganese alloys reached 11.8 million metric tons.
  • Out of a manganese ore production of over 34 million tons per year, 13 million tons come onto the international market. A few producing
    countries, Australia, Brazil, Gabon and South Africa, account for over 85% of the world’s supply.
  • Today, most of the manganese requirements of industrialized countries are supplied in the form of alloys. As a result, the UK and Germany have has almost completely abandoned local production of manganese alloys and the USA is now only a minor producer. In Europe, countries such as France, Norway and Spain have continued to be large exporters of these ferro-alloys.
  • World demand for manganese depends directly on the needs of the steel industry.
  • There are numerous grades of steel and each requires a different amount of manganese.
  • Unit consumption is determined by calculating the average requirement of manganese per ton of steel.
  •  Some manganese which is to be converted into steel is present in the iron (hot metal) coming either from the iron ore charge or from the addition of manganese ore to the blast furnace.
  • The production capacity of electrolytic Manganese matalsin exceeded 300,000t. The number of electrolytic manganese matal plants is around 60. The annual capacity of the largest one is 200,000t.
