WolframiteWikipedia

Wolframite, (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and hübnerite (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.


Wolframite: The mineral wolframite information and pictures

Wolframite is not scientifically classified as an individual mineral species by the IMA.However, it is universally recognized as a mineral series, with the minerals Huebnerite and Ferberite being its end members. Huebnerite is the manganese-rich end member, and Ferberite is the iron-rich end member.


Wolframite: Mineral information, data and localities.

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.
