Tungsten (W) - Properties, Applications

2002-1-21 · Tungsten is usually mined underground. Scheelite and/or wolframite is frequently located in rather narrow veins which are slightly inclined and often widen with the depth. Open pit mines exist but are rare. Most tungsten ores contain less than 1.5% WO 3 and ore dressing plants are always in close proximity to the mine.

The mineralogy of Tungsten

Deposits of wolframite are generally from magmatic or hydrothermal origin. Concentration of workable ores is usually between 0.3% and 1.0% WO 3. Scheelite, another important ore or tungsten, is a calcium tungstate and can be found in contact metamorphic skarns, high-temperature hydrothermal veins/greisens and occasionally in granitic pegmatites.
