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 (often in combination with iron), and in many minerals. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. Historically, manganese is named for various black minerals (such as pyrolusite) from the same region of Magnesia in Greece which gave names to similar-sounding magnesium, Mg, and magnetite, an ore of the element iron, Fe. By the mid-18th century, Swedish chemist Carl Wilhelm Scheelehad used pyrolusite to produce chlorine. Scheele and others were aware that pyrolusite (now known to be manganese dioxide) contained a new element, but they were not able to isolate it. Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, byreducing the dioxide with carbon. Manganese phosphating is used as a treatment for rust and corrosion prevention on steel. Depending on their oxidation state, manganese ionshave various colors and are used industrially as pigments. The permanganates of alkali and alkaline earth metals are powerful oxidizers. Manganese dioxide is used as the cathode (electron acceptor) material in zinc-carbon and alkaline batteries. In biology, manganese(II) ions function as cofactors for a large variety of enzymes with many functions. Manganese enzymes are particularly essential in detoxification of superoxide free radicals in organisms that must deal with elemental oxygen. Manganese also functions in the oxygen-evolving complex of photosynthetic plants. The element is a required trace mineral for all known living organisms. In larger amounts, and apparently with far greater activity by inhalation, it can cause a poisoning syndrome in mammals, with neurological damage which is sometimes irreversible.
Manganese is a brittle metal. Physically, it is a hard gray-white to silver metal that looks like iron. As an essential ingredient of steel, Manganese is the 12th most abundant element which is widely distributed on the earth’s crust. It is also the 4th most used metals in terms of tonnage. In 2010-11, SGX Minerals started operation Manganese Mine at different locations in Vizianagaram districts of Andhra Pradesh.

1,Tabletted additives for alloying aluminum have been in use for recent decades.These tablets(also named alloy compact)can be used as master alloys to produce aluminum alloys.They provide an efficient and economic way of making elemental additions such as titanium,iron.manganese,chromium,zinc,nickel and copper in casthouses world-wide for the manufacture of high-quality aluminium alloys in applications such as rolling ingot for foilstock and canstock,billet for precision extrusions and high-quality foundry casting alloys.
