 | This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |

[edit]Tungsten Ore
Article body
[edit]Tungsten ore is a rock from which the element tungsten can be economically extracted. The ore minerals of tungsten include wolframite, scheelite, and ferberite (an Fe-rich endmember of a solution series with hubnerite, a Mg-rich tungsten oxide).[1] Tungsten is used for making many alloys.
Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions.[2] Such deposits include but are not limited to veining and stockwork, disseminated or greisen, skarns, stratabound, or porphyry deposits.[1][3][4] It is often associated with cassiterite in granitoid type stockwork systems, such as the Pilok tin-tungsten deposit at the border of Burma and Thailand.[5]
Currently, the largest producer and consumer of tungsten bearing ore is China.[6] China also has the largest reserves at nearly 60% of global output in 2019.
