Per Agricola, it is derived from "volf," "wolf," and "rahm," "ram," for "froth", "cream," "soot" (Latin = Lupi spuma), perhaps in allusion to an objectionable scum or substance formed during the smelting of tin ores containing tungsten; possibly also derived from "lupus" and "wolf", which were alchemists' terms for antimony, for which it may have been mistaken as an ore.

Wolframite (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and huebernite (Mn 2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.

Below is a gallery of crystallized ferberite and huebnerite for sale from John Betts - Fine Minerals in New York City, NY.In the past, ferberite and huebnerite would be grouped under the now obsolete name of Wolframite, which is now the formal group name.

Wolframite is not actually considered a unique mineral, but as a part of a mineral series, which includes huebnerite (manganese-rich) and ferberite (iron-rich). Wolframite sits closer to the middle of the series, as its manganese and iron content are generally more equal.

Wolframite is a comparatively rare mineral, and is normally found usually with cassiterite and associated also with scheelite, bismuth, quartz, pyrite, galena, sphalerite, etc. It is found in fine crystals from Schlaggenwald, Bohemia, and in the various tin districts of Saxony and Cornwall.

Wolframite is the intermediate between ferberite and hübnerite. Along with scheelite, the wolframite series are the most important tungsten ore minerals.

It was collected in 1953 but there is no detailed indication about the quarry it is originated from. Size of the crystal: 7 x 6 mm Collection & photo: Alain TUEL

Wolframite, sp. gr. 7.1 to 7.5, tungstate of iron and manganese, is feebly magnetic; specimens from some localities are reported to be strongly magnetic. Wolframite frequently accompanies cassiterite in tin ores, and on account of their similar specific gravities (cassiterite 6.4 to 7.02) these minerals may not be separated from each other by specific-gravity methods. The method usually ...

WOLFRAMITE (Fe,Mn)WO4: Is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe2+ rich) and hübnerite (Mn2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.

Ferberite is the iron-rich end member of the Wolframite series.It is not always individually distinguished and is sometimes just classified as Wolframite. The presence of iron in its structure is responsible for its black color and opacity in relation to Huebnerite.Ferberite is named after German mineralogist Dr. Moritz Rudolph Ferber (1805-1875).
