Wolframite is an iron, manganese, and tungstate mineral with a chemical formula of (Fe,Mn)WO 4 that is the intermediate mineral between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich). [4] Along with scheelite, the wolframite series are the most important tungsten ore minerals.

Note: "Wolframite" usually has a chemical composition covering the range between Hübnerite and Ferberite. Rarely, "wolframite" could also correspond to other, visually very similar members of the wolframite group.

Material usually chemically between Hübnerite and Ferberite with unspecified chemical composition. Rarely, "wolframite" could also correspond to other members of the wolframite group. Occurs in high-temperature hydrothermal veins, in greisen, granitic pegmatites; in alluvial and eluvial deposits.

Science & Origin of Wolframite. Wolframite is an iron manganese tungsten mineral that crystallizes in striated, tabular, and prismatic crystals, as well as bladed clusters, granular, and masses. The name “wolframite” has also been used to describe a group of minerals with a similar chemical composition.
