Ferberite

Tungstate mineral

Ferberite is the iron of the manganese series. The manganese endmember is hübnerite. Ferberite is a black monoclinic (II) tungstate 4.

Ferberite and hübnerite often contain both divalent cations of iron and manganese, with wolframite as the intermediate species for which the solid solution series is named.

Ferberite occurs as granular masses and as slender prismatic crystals. It has a Mohs hardness of 4.5 and a specific gravity of 7.4 to 7.5. Ferberite typically occurs in pegmatites, and high temperature hydrothermal It is a minor ore of tungsten.

Ferberite was discovered in 1863 in Sierra Almagrera, Spain , and named after the German mineralogist Moritz Rudolph Ferber (1805–1875). * Twinned Ferberite, Tazna Mine, Atocha-Quechisla District, Nor Chichas Province , Bolivia. 4.8 x 4.0 x 3.6 cm. * Ferberite - Cínovec / Zinnwald, Erzgebirge; Krusné Hory Mts, Saxony & Ústí Region (Bohemia), Germany & Czech Republic
