Extraction of Tungsten JXSC Machine
Tungsten is a widely distributed element, almost found in all kinds of rocks, but its content is relatively low. It is possible to form deposits as commercial ore mining by enriching the geological processes. Tungsten ores are mainly divided into wolframite and scheelite. Wolframite is the most important ore to extract tungsten.
Classification of tungsten oresMetalpedia
Tungsten ores. Tungsten does not occur naturally in its pure metallic state; rather, it is found in several ores, but only two kinds of tungstenbearing mineral rocks, called wolframite and scheelite, are mined commercially. Wolframite accounts for about 70% of the total tungsten resources in the world, and scheelite accounts for about 30%.
