Manganese
is a little-known element other than to a small
circle of technical specialists who are predominantly
metallurgists and chemists. Yet it is the fourth
most used metal in terms of tonnage, being ranked
behind iron, aluminum and copper, with in the order
of 38 million tons of ore being mined annually (2007).
Manganese
has numerous applications which impact on our daily
lives as consumers, whether it be of objects made
of steel, of portable batteries, or of aluminum
beverage cans. In each case manganese plays a vital
role in improving the properties of the alloys and
compounds involved in each specific application.
One vital feature of manganese, which is not widely appreciated, is its role as an essential element in maintaining human health. Recommended daily dietary intake levels have been established by US regulatory authorities in an effort to ensure the maintenance of good health. |
