Manganese History
First identified by Scheele, Bergman and other experts as an element and isolated by Gahn in 1774, with the reduction of manganese dioxide with carbon.

Manganese minerals are widely spread in many forms; oxides, silicates, carbonates are the most common compounds. The discovery of a large number of manganese compounds in the bottom of the ocean is the source of the manganese content of 24%, along with other elements with less content.
Most of the manganese compounds currently found in Russia, Brazil, Australia, Africa sSelatan, Gabon, and India. Irolusi and rhodokhrosit mineral manganese is most often found. Metals, manganese is obtained by reduction of manganese oxide with sodium, magnesium, aluminum, or by electrolysis.

Manganese Properties
Manganese grayish white, with a hard but brittle nature. Manganese is very reactive chemically, and decomposes cold water slowly. Manganese is used to form many important alloys. In steel, manganese improves the quality forging both in terms of strength, hardness, and hardenability.
With aluminum and bismuth, especially with small amounts of copper, forming a ferromagnetic alloy.
Manganese metal is ferromagnetic after a given treatment. The pure metal exists as a form allotropik with four types. One of them, alpha type, unusually stable at high temperatures, whereas the type of gamma manganese, which turned out to be an alpha at high temperatures, said flexible, easy to cut and forged.

Usefulness of Manganese
Manganese dioxide (as pirolusit) is used as depolariser and dry cell batteries and to remove the green color in the glass caused by iron impurities. Manganese violet color itself gives the glass. Dioxide is useful for the manufacture of oxygen and chlorine, and in drying black paints.
Compounds permanganate is a strong oxidizing agent and is used in quantitative analysis and in medicine. Manganese is also widely spread in the body. Manganese is an essential element for the use of vitamin B1.
Benefits and function of Manganese
Manganese market prospect is very dependent on the world steel industry. Currently 90 percent of the production of manganese is consumed by the steel industry and for this purpose usually used a mixture of iron manganese, which feromangan.
Feromangan produced by reduction of a mixture of iron and manganese oxides with carbon. The most important manganese ore is pirolisit, MnO2 Manganese is one of the mining products with outstanding usability.
Commodities are included in the group of twelve mineral in the earth's crust into raw materials which are not replaceable in the world steel industry. Ferro Manganese and Manganese are two forms of silico manganese steel industry which is widely used.
Manganese is also used for the production of dry batteries, ceramics, glass and chemicals.
Manganese is essential to iron and steel production. Manganese is a key component of low-cost stainless steel formulations and certain widely used. Manganese is used in steel alloys to increase the favorable characteristics such as strength, hardness and durability. Manganese is used to make the glass and making glass achromatic color purple.
Manganese dioxide is also used as a catalyst. Additionally Manganese is used in the electronics industry, where manganese dioxide, either natural or synthetic, which is used to produce manganese compounds which have a high electrical resistance; among other applications, is used as a component in every television set.
Manganese is a mineral that is used by some to help prevent bone loss and reduce the annoying symptoms associated with premenstrual syndrome (PMS). Methylcyclopentadienyl manganese tricarbonyl is used as an additive in unleaded gasoline to boost octane and reduce engine knocking. The manganese in the unusual organometallic compound is in the oxidation state 1.
Manganese (IV) oxide (manganese dioxide, MnO 2) is used as a reagent in organic chemistry for the oxidation of benzylic alcohols (ie adjacent to an aromatic ring). Manganese dioxide has been used since antiquity to neutralize oxidative greenish tinge in glass caused by trace amounts of iron contamination. MnO 2 is also used in the manufacture of oxygen and chlorine, and in drying black paints.
In some preparations it is a brown pigment that can be used to make paint and is a constituent of natural umber. Manganese (IV) oxide is used in the original type of dry cell battery as an electron acceptor from zinc, and is the blackish material found when opening carbon-zinc type flashlight cells. Manganese dioxide is reduced to manganese oxide-hydroxide MnO (OH) during discharging, preventing the formation of hydrogen at the anode battery.
Manganese is also important in photosynthetic oxygen evolution in chloroplasts in plants.
Manganese Handling
Exposed to manganese dust, vapor and compounds should not exceed 5 ppm even for a very short period because of the level of toxicity of the element.
