iron manganese tungsten
Noun: - A specific mineral, consisting of a crystalline solid solution series between the endmembers ferberite (iron tungstate, FeWO₄) and hübnerite (manganese tungstate, MnWO₄). It is the chief commercial source of the element tungsten.
This term is a technical, mineralogical name. It is used primarily in geology, mining, and materials science contexts to refer to the natural, mixed-composition ore of tungsten. - The geologists identified the black, dense veins in the granite as iron manganese tungsten. - Tungsten is primarily extracted from the mineral iron manganese tungsten.
- The mineralogical series is more formally referred to as the wolframite series. "Iron manganese tungsten" is a descriptive chemical name for this series.
- In economic geology, it is categorized as a strategic mineral due to the critical importance of tungsten in industrial and military applications.
- Wolframite: The more common mineralogical name for the iron-manganese tungstate series.
- Ferberite: The iron-rich end member (FeWO₄) of the series.
- Hübnerite: The manganese-rich end member (MnWO₄) of the series.
- Tungsten ore: A general term for minerals from which tungsten is extracted, with iron manganese tungsten (wolframite) being the principal one.
- Wolframite (This is the direct and most frequently used synonym in scientific literature).
This term has a single, precise meaning as a mineral name. It does not refer to a simple mixture of the three metallic elements (iron, manganese, tungsten), but to a specific crystalline chemical compound where they are bound in a tungstate structure.
-
a mineral consisting of iron and manganese tungstate in crystalline form; the principal ore of tungsten; found in quartz veins associated with granitic rocks
