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.

A superlarge deposit—Kalahari manganese ore field

Study of carbonate inclusions in the Mamatwan-type oxide ores (braunite lutites) made it possible to reveal residual microbial structures in them. Their presence in manganese ores, the type of manganese oxide mineralization, isotope signatures of manganese carbonates, and available literature data on the geology of the Kalahari manganese field suggest that manganese ore formation was
