(Fe,Mn)WO₄ - The main commercial source, forming dark crystalline masses in high-temperature veins. Found primarily in China, which controls 85% of global production.
CaWO₄ - White to yellow crystals that fluoresce brilliant blue under UV light. Major deposits in Australia, Peru, and the western United States provide this premium Tungsten ore.
Iron-rich and manganese-rich varieties of wolframite found in Bolivia's legendary Llallagua mine and Colorado's historic mining districts.
Jiangxi Province's Dayu Mine and Hunan Province's Shizhuyuan Mine dominate world supply. China's tight export controls make Tungsten a strategic metal.
Siberia's Tyrnyauz deposit in the Caucasus Mountains contains both Tungsten and molybdenum in one of the world's largest polymetallic deposits.
Northwest Territories' Cantung Mine produces high-grade Tungsten ore from one of the richest deposits outside China.
Colorado's Boulder County and California's Eastern Sierra contain historic Tungsten mines that supplied America during both World Wars.
Tungsten concentrates in hydrothermal veins where superheated water (300-600°C) carries dissolved Tungsten compounds deep underground. As the solution cools, Tungsten precipitates with quartz, forming the characteristic "wolframite veins" that miners seek.
Most deposits form near granite intrusions where magma's heat drives the hydrothermal circulation that concentrates Tungsten from trace amounts in surrounding rocks.
Tungsten's extreme hardness makes extraction difficult. Ore must be crushed to powder, then separated using magnetic and gravity techniques. The resulting concentrate requires high-temperature hydrogen reduction to produce pure Tungsten metal - a process consuming enormous amounts of energy.
Tungsten's rarity and strategic importance led the U.S. to classify it as a "critical mineral." During WWII, Tungsten was so valuable it was called "the metal that won the war" due to its use in armor-piercing ammunition and jet engines.

Confusion reigned over tungsten's name! Germans called it "wolfram" (wolf's foam) because it interfered with tin smelting like a ravenous wolf. Swedes preferred "tungsten" (heavy stone). Today, both names coexist: element symbol W honors wolfram, while English-speakers say tungsten.
