9. Distribution map of fluorite deposits in China.

South Africa, Mexico, Mongolia, Russia, the United States, Thailand, Spain and other places also produce fluorite. China is one of the countries with the largest number of fluorite minerals in the world, mainly produced in Chenzhou area in southeastern Hunan, and also produced in Zhejiang, Fujian and other places. The famous fluorite producing areas in China are: fluorite mine in De 'an County, Jiangxi Province, fluorite mine in Yang Shulian County, Pingquan County, Hebei Province, fluorite mine in Baixin County, Lingshou County, Hebei Province, and fluorite mine in Qiulinggou County, Inner Mongolia Autonomous Region.

10. Performance

Fluorite is also called fluorite. A common mineral in nature, which can coexist with many other minerals, has five effective varieties. Crystals are octahedrons and cubes. It has the property of perfect cleavage. Because of its brittleness and softness, it is not often used as a gem. In industry, fluorite is the main source of fluorine, and fluorine and its compounds can be extracted and prepared. Fluorite specimens are bright in color and beautiful in crystal form, which can be used for collection, decoration and carving handicrafts.

1 1. Meaning

There is an old legend about fluorite. On a hill in ancient India, locals found many cobras here, and these snakes often gathered around a boulder. Curious people decided to find out. People climbed the hill in the dark and found that the huge stone gave off a faint blue light. The phototaxis makes the flying insects pounce on the stone, and the stone becomes the food for the long-awaited frog, and the frog army attracts cobras to round it up. It turns out that snakes gather here to keep "stones" and cure "frogs". This stone is fluorite.
