Frequently Asked Questions
Scheelite is a mineral composed of calcium tungstate (CaWO4) and is a major ore of tungsten.
It is pronounced /ˈʃiːlaɪt/ (SHEE-light), named after the Swedish chemist Carl Wilhelm Scheele.
It is typically found in high-temperature hydrothermal veins, skarns, and granitic pegmatites.
It is a crucial source of tungsten, a metal used in hard steels, filaments, and electrical contacts.
