Many centuries ago mid-European tin smelters observed that when a certain mineral was present in the tin ore, their yield of tin was much reduced. They called this mineral 'wolfs ' because, they said, it devoured the tin much like a wolf would devour a sheep! Thus over time the name 'wolframite' evolved for this tungsten-containing ore.
Tungsten Minerals: The only two tungsten minerals of any importance are two tungstates or oxides, their relative values being determined by the measure used to determine mine ore grades and mine concentrate grades, i.e. the tungsten trioxide or WO3, content:. Scheelite, a calcium tungsten oxide, CaWO4 – contains 80.5% WO3. Wolframite, an iron-manganese tungsten oxide, (Fe, Mn)WO4 – the ...

Classification of tungsten ores; Tungsten ores; Tungsten does not occur naturally in its pure metallic state; rather, it is found in several ores, but only two kinds of tungsten-bearing mineral rocks, called wolframite and scheelite, are mined commercially. Wolframite accounts for about 70% of the total tungsten resources in the world, and scheelite accounts for about 30%.
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.
Tungsten does not occur naturally in its pure metallic state, but is always found as an ore such as wolframite or scheelite. Tungsten ore is not currently mined in the United States due to financial and environmental considerations although the U. S. has substantial deposits.
