The Mineral huebnerite
Huebnerite is the manganese-rich end member of the Wolframite series.It is not always distinguished individually and is sometimes just classified as Wolframite. An increase of iron in its structure tends to give it a more black color, decrease transparency, and increase its density.Huebnerite is named after German metalurgist and mining engineer Adolf Hübner.
