(Fe2+)WO4 to (Mn2+)WO4
4 - 4½
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.
Material chemically intermediate between Hübnerite and Ferberite with unspecified chemical composition.

Occurs in high-temperature hydrothermal veins, in greisen, granitic pegmatites; in alluvial and eluvial deposits.

Other Information:
Slightly magnetic. Decomposed by aqua regia with the separation of tungstic oxide.

Forms pseudomorphs after Scheelite. Often more or less completely replaced by Scheelite. Pseudomorphs of Quartz, Hematite, Marcasite, and Kaolinite after Wolframite noted.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
