Tungsten ore - Wikipedia
Tungsten ore is a rock from which the element tungsten can be economically extracted. The ore minerals of tungsten include wolframite, scheelite, and ferberite. Tungsten is used for making many alloys.
Tungsten - Wikipedia
Tungsten is extracted from its ores in several stages. The ore is eventually converted to tungsten(VI) oxide (WO 3), which is heated with hydrogen or carbon to produce powdered tungsten. [45] Because of tungsten's high melting point, it is not commercially feasible to cast tungsten ingots.

Wolframite is highly valued as the main source of the metal tungsten, a strong and very dense material with a high melting temperature used for electric filaments and armor-piercing ammunition, as well as hard tungsten carbide machine tools.
Tungsten - Minerals Education Coalition
Named from the Swedish word meaning “heavy stone,” tungsten is a gray-white metal that is stable and unaffected by air, acids or bases. It has the highest melting point of any metal and often is used in alloys that must resist great amounts of heat, such as light-bulb filaments.
