Fluorapatite is a mineral that belongs to the apatite group and the most common specie in the apatite group. It was first discovered in 1823 by German mineralogist, Abraham Gottlob Werner.
The name “apatite” is derived from the Greek word “apatein,” meaning “to deceive,” because of its similar appearance to several other minerals. Fluorapatite got its name due to the significant presence of fluorine in its composition.
Fluorapatite is commonly found in igneous rocks, such as granite and pegmatite, as well as in hydrothermal veins and metamorphic rocks. It occurs in various parts of the world, including Brazil, Russia, Madagascar, Canada, the United States, and South Africa.
Fluorapatite has various applications in various fields. It is used sometimes as a gemstone due to its pleasing color range, including yellow, green, blue, violet, and purple. However, it is not very commonly used for jewelry.

Apatite minerals, including fluorapatite, are the primary source of phosphorus, which is an essential nutrient for plants. Phosphorus in fluorapatite can be extracted and used in the manufacturing of fertilizers. Fluorapatite is also used to produce phosphoric acid, which is utilized in various industries such as food, beverages, and detergents.
Fluorapatite is the main source of fluoride used in water fluoridation, dental products like toothpaste, and other fluoride supplements that aid in dental health.
Fluorapatite has a hardness of 5 on the Mohs scale, making it relatively durable with a Hexagonal crystal system. It occur in various colors, including yellow, green, blue, violet, and purple with a vitreous to subresinous lustre. It’s
density ranges from 3.1 to 3.2 g/cm3.
The global value of fluorapatite primarily lies in its use as a source of phosphate for fertilizers and phosphoric acid production. Phosphorus is a vital nutrient necessary for crop growth and food production.
Therefore, fluorapatite plays a significant role in global agriculture and food security. It’s global value depends on the global demand for fertilizers and phosphoric acid, which fluctuates based on agricultural needs and economic conditions.
