Fluorite can be found in many places, but the main areas for Fluorite are China, Mexico, and Western Europe. About 4 million tones of Fluorite are produced annually. Mostly, Fluorite can be found in rocks, coal and clay. Fluorite is the 13th most abundant element in the earth’s crust. Some soils can approximately 330 ppm of fluorine. | Fluorite can be found in many places, but the main areas for Fluorite are China, Mexico, and Western Europe.
