Mar 30, 1999 · Manganese oxide minerals have been used for thousands of years—by the ancients for pigments and to clarify glass, and today as ores of Mn metal, catalysts, and battery material. More than 30 Mn oxide minerals occur in a wide variety of geological settings. They are major components of Mn nodules that pave huge areas of the ocean floor and bottoms of many fresh-water lakes.
Manganese - Wikipedia
This is done by percolating natural gas through the bottom of the heap; the natural gas provides the heat (needs to be at least 850 °C) and the reducing agent (carbon monoxide). This reduces all of the manganese ore to manganese oxide (MnO), which is a leachable form.

Manganite - Wikipedia
Manganite is a mineral composed of manganese oxide-hydroxide, MnO, crystallizing in the monoclinic system. Crystals of manganite are prismatic and deeply striated parallel to their length; they are often grouped together in bundles. The color is dark steel-grey to iron-black, and the luster brilliant and submetallic. The streak is dark reddish brown. The hardness is 4, and the specific gravity is 4.3. There …
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.
