#25 - Manganese - Mn
Manganese ore was first confused with magnetic iron ore. One source of manganese is in nodules on the ocean floor. Miners and steel workers exposed to high levels of manganese dust in the air may develop manganism, which can cause mental and emotional disturbances or disturb their movement like in Parkinsons disease.

The Properties and Effects of Manganese as an Alloying Element
Oct 05, 2016 · Effects of Manganese as an Alloying Element. Manganese is used as an alloying element for many different applications. Manganese is a key component of steel. In fact, this stone element is present in all commercially available steels and is responsible for the steel’s hardness and strength, but to less of an extent than carbon.
