Manganese Rocks and Ores - ScienceDirect

Jan 01, 2017  This chapter lists all basic chemical characteristics of the element Mn and the area of its application. In nature, manganese is concentrated in various manganese rocks of sedimentary and hydrothermal-sedimentary genesis consisting predominantly (> 50%) of manganese minerals (Mn content—15–20% and greater); commonly this term is used in the literature as a synonym for manganese ore.

The mineralogy of Manganese

Most widespread minerals containing Manganese; This list of minerals containing Manganese is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Manganese mineral ...

It was discovered 1774 by Johann Gahn. Manganese easily reacts with water and air. On Earth, manganese is never found as a free metal, but it is found in a number of minerals. The most important of these minerals is pyrolusite, the main ore mineral for manganese. Manganese is essential to iron and steel production.
