Introduction: what is manganese?

Manganese (Mn). A very solid transition metal, it represents 0.1% of the components of the earth's crust (12th in terms of abundance), it is available united with other elements such as iron (Fe) but it is not equally distributed around the globe, where 80% of the manganese ore is in South Africa.
In nature, manganese does not exist in pure form. It was isolated for the first time in 1770 by the Austrian chemist Ignatius, but that does not mean that the man did not use manganese before, it was used by cave artists in France 30 thousand years ago and it was also used in the manufacture of glass and in the dyeing of pottery.
