It is used in high-strength applications, such as furnaces, missiles, dental drills and other cutting tools. The symbol for tungsten, W, comes from tungsten’s Latin name Wolfram. The Latin name is derived from the tungsten mineral wolframite. Biological Benefits. Tungsten is used by a small number of enzymes in a fashion similar to molybdenum.

Chemically pure tungsten was not produced until some years later by reduction of the oxide with hydrogen under heat. Occurrence. The occurrence of tungsten in the earth's crust is very low (about 0.0064% by weight). The most important tungsten ores are wolframite and scheelite.

Relation to Mining Tungsten is retrieved from the ore minerals scheelite (CaWO4, calcium tungstate) and wolframite ((Fe,Mn)WO4, iron-manganese tungstate). A significant amount of tungsten is recovered through recycling of scrap tungsten products.

Wolframite, (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.
