Manganese Minerals Education Coalition

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. The U.S., Japan, and Western Europe are all nearly deficient in economically mineable manganese.

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.

About this site

Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions. This would ensure much more consistent manganese content in the hot metal.

PROPERTIES OF MANGANESE ORES AND THEIR CHANGE IN THE ...

Groote Eylandt (GE) ore is a high-grade ore with a manganese content of 55 wt% (71 wt% MnO). The only phase identified in GE ore by XRD was MnO2 (pyrolusite). However, optical analysis and SEM revealed the complex mineralogical structure of the ore. Apart from pyrolusite, GE ore contained iron silicate and silica; pyrolusite grains were distinguished by the colour given by different impurities.
