International strategic mineral issues summary report: tungsten. Scheelite and wolframite are the principal minerals currently mined for tungsten. Both occur in hard-rock deposits; wolframite is also recovered from placer deposits. Most current mine production of tungsten is from vein/stockwork, skarn, porphyry, and strata-bound deposits.

Summary. Tungsten has the highest melting point of all non‐alloyed metals. Tungsten deposits usually occur within, or near to, orogenic belts resulting from subduction‐related plate tectonics. Tungsten mining techniques are similar to many other metals of similar occurrence.

The growth in technological innovation that has occurred over the past decades has, in part, been possible because an increasing number of metals of the periodic table are used to perform specialized functions.
However, there have been increasing concerns regarding the reliability of supply of some of these metals. A main contributor to these concerns is the fact that many of these metals are Cited by: Strategic Metals and National Defense: Tungsten in World War II (and Beyond) By Ronald H.
