-Fluorine can be found in many places, but the main areas where Fluorine is found is in China, Mexico, and Western Europe. About 4 million tons of Fluorite are produced annually. Mostly, Fluorite can be found in common rock forming minerals, including fluorite. It occurs in both igneous and sedimentary rocks. It also occurs as minerals such as apatite, topaz, simple halides, also in silicates such as muscovite and a range of amphibole and mica minerals. Fluorine is the 13th most abundant element in the earth’s crust. Some soils can hold approximately 330 ppm of Fluorine. There are about 0.6 ppb of Fluorine present in the atmosphere.
