Wolframite is not scientifically classified as an individual mineral species by the IMA.However, it is universally recognized as a mineral series, with the minerals Huebnerite and Ferberite being its end members. Huebnerite is the manganese-rich end member, and Ferberite is the iron-rich end member.
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 ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions.

Tungsten is commonly alloyed with carbon forming tungsten carbide which has a very high melting point and increased hardness. 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 Tungsten Axe is an early game Axe, being stronger than both the Iron and Lead Axe, and weaker than both the Gold and Platinum Axe. It has an alternative version, the Silver Axe, which is slightly weaker. Like all Axes, it is used to cut down Trees, Cacti, and Giant Glowing Mushrooms.

Tungsten is found in several ores, but only two kinds of tungsten-bearing 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%.
The Cantung mine, owned and operated by the North American Tungsten Corporation Ltd. (NATCL), is a tungsten mine in the Northwest Territories, Canada. Cantung is one of the largest operating tungsten mines outside of China. The mine consists of both open pit and underground operations, which extract ore from a scheelite-chalcopyrite bearing skarn.
Tungsten is also used as the filament in halogen tungsten lamps. These lamps use halogens like bromine and iodine to prevent the tungsten filament from degrading and are therefore more energy efficient than standard incandescent light bulbs. High speed steel (which can cut material at higher speeds than carbon steel), contains up to 18% tungsten.
