Tungsten occurs principally in the minerals scheelite, wolframite, huebnerite, and ferberite. In the United States these minerals occur most notably in California and Colorado. Elsewhere they are found in China, the Buryat republic of Russia, Kazakhstan, South Korea, Bolivia, and Portugal.

Where is tungsten found in nature?

Most tungsten resources are found in China, South Korea, Bolivia, Great Britain, Russia and Portugal, as well as in California and Colorado. Though it is found in these many places, 80 percent of world's supply is controlled by China, according to the BBC.

How is tungsten formed naturally?

Instead, tungsten is thought to be formed from the explosions of massive stars. Each supernova explosion has so much energy, that these newly created elements are jettisoned at incredible speeds of 30,000 km/s, or 10% of the speed of light – and that's how they get dispersed throughout the universe.
