- Facts About Tungsten
- Tungsten naturally occurs in the minerals wolframite, scheelite, huebnertie and ferberite. China may have about 75 percent of the world's tungsten resources and other deposits are located in California, Colorado, South Korea, Bolivia, Russia and Portugal.
- Tungsten: Heavy Metal (Including Cello)
- It is only present in various chemical compounds. For industrial purposes, the two most important tungsten-bearing minerals are wolframite ((Fe,Mn)WO4) - or, as some would like to call it Ferberite-Huberite, and scheelite (CaWO4).
Ferberite is described in multiple online sources, as addition to our editors' articles, see section below for printable documents, Ferberite books and related discussion.
