Manganese in igneous rocks commorly occurs as a minor component in many minerals, such as the pyrorenes, olivines, and amphiboles, but independent manganese minerals are scarce. Combined or ionic manganese can occur at oxidation levels from + 1 to +7. In natural environments, however, some of these oxida-

Manganese is a very brittle, hard, pinkish-gray metal. It is a reactive metal, chemically active with water, air and most acids. It hardens and strengthens steel when alloyed with it. It also is used in alloys with aluminum, copper and antimony to create highly ferromagnetic compounds, although none of these elements are naturally ferromagnetic.

Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.
