  • 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 ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions.

  • Tungsten Manufacturers | Tungsten Suppliers

    Tungsten does not occur naturally in a pure metal form; rather, it is extracted from ore in early stages of tungsten processing. (Wolframite and scheelite are the two main types of ore that tungsten is extracted from.) Raw tungsten is unsuitable for use due to its extremely brittle nature.

  • Extracting Tungsten from Wolframite Gold Ore

    The flowsheet study previously shown for tungsten was devised for a simple tungsten ore free of other heavy minerals. The first consideration of any tungsten ore is to recover the mineral as coarse as possible and avoid sliming and overgrinding by stage crushing and grinding. This is necessary because of the friable nature of all tungsten minerals.
