From the Mineral Information Institute: Tungsten is retrieved from the ore minerals scheelite (CaWO4, calcium tungstate) and wolframite ((Fe,Mn)WO4, iron-manganese tungstate). Of the world’s tungsten reserves, over 90% are outside the United States. Of these resources, nearly half are found in China, and Canada and Russia also have large reserves. About one-third of the U.S. imports of tungsten are from China, Russia provides about 25%, and a variety of other nations provide the rest. A significant amount of tungsten is recovered through recycling of scrap tungsten products. Recycled tungsten in the US accounts for nearly one-third of the tungsten consumed. Major production of tungsten concentrates come from Austria, Bolivia, Canada, China, Portugal, and Russia. quote:

ORIGINAL: thompsonx You will note that the U.S.'s major source of tungsten is encompased by the way that the demarkation line is drawn. You will note that the line is "nominally on the 38th. parallel but that the demarkation line extends north of the 38th parallel to include this major tungsten source. What that only back then? Korea's not listed as a supplier nowadays. Is the U.S. listed as a supplier of rock drilling bits to Russia and China?Berkshire Hathaway controls this company, TaeguTec the largest exporter of Tungsten in S. Korea
