wolframite
C2Technical/Scientific
Definition
Meaning
A brown to black mineral consisting of iron manganese tungstate, the chief ore of tungsten.
In historical and industrial contexts, the primary source material for the extraction of tungsten metal, which is crucial for high-strength steel alloys, filaments, and other applications.
Linguistics
Semantic Notes
Used almost exclusively in geology, mining, metallurgy, and industrial chemistry. The name is also a historical synonym for the element tungsten itself.
Dialectal Variation

Context Usage
Business
In mining company reports: 'The quarterly yield of wolframite increased by 12%.'
Academic
In a geology paper: 'The wolframite samples exhibited a solid-solution series between ferberite and hübnerite.'
Everyday
Virtually never used in everyday conversation.
Technical
In a metallurgy manual: 'Reduction of wolframite yields tungsten powder and iron-manganese slag.'
Examples
By CEFR Level
- The museum displayed a dark, shiny sample labelled 'wolframite'.
- Tungsten is often extracted from a mineral called wolframite.
- The economic viability of the deposit hinges on the wolframite-to-scheelite ratio.
- Spectroscopic analysis confirmed the wolframite's predominant ferberite composition.
Learning
Memory Aids
Mnemonic
Think: 'WOLFramite' contains a 'wolf' - a wolf is strong, and tungsten from wolframite makes strong steel.
Conceptual Metaphor
SOURCE OF STRENGTH (as the primary source of tungsten, a metal synonymous with hardness and durability).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation of 'вольфрамит' is correct and identical. Be aware 'wolfram' is the international name for tungsten ('вольфрам').
Common Mistakes
- Misspelling as 'wolframite' (should be 'wolframite'). Confusing it with 'wolfram', which is the element name.

FAQ
Frequently Asked Questions
No. Wolframite is a mineral (iron manganese tungstate) that contains tungsten. Tungsten (also called wolfram) is the chemical element extracted from wolframite and other ores.
No, it is a highly specialized technical term used almost exclusively in geology, mining, and metallurgy.
The name derives from 'wolfram', an old German name for tungsten, which itself has obscure origins possibly relating to the mineral's interference with tin smelting ('wolf's foam').
Yes. Wolframite is a solid-solution series between two endmember minerals: ferberite (iron-rich) and hübnerite (manganese-rich). The composition affects its specific gravity and color.
