Among its many applications, tungsten is used in metalworking, mining, and stone-cutting tools, high-temperature technologies, lighting, catalysts, pigments, armaments, and aerospace. A list of 35 critical minerals was published by the United States Department of Interior in May 2018, including tungsten. The most likely source of secondary tungsten minerals is hydrothermal alteration or supergene weathering rather than atmospheric weathering. Grey et al. (2006) reported that primary tungsten minerals, like ferberite and scheelite, may undergo hydrothermal alteration, which may result in secondary tungsten minerals.
