Apatite is the main mineral source of phosphorus used in phosphate fertilizer.
Apatite is a group of phosphate minerals, chiefly fluorapatite, chlorapatite, and hydroxylapatite. Natural phosphate rock is mined, processed, and converted into phosphoric acid or other phosphate products used in agricultural fertilizers. Phosphorus is an essential nutrient for plant energy transfer, roots, and reproduction.
Apatite also occurs in biological systems. Hydroxylapatite is a major inorganic component of vertebrate bones and teeth, where it forms tiny crystals within an organic framework. Gem-quality apatite can be blue, green, yellow, or other colors, but it is generally softer and less durable than many popular gemstones. Its name comes from a Greek word meaning deception because its appearance can resemble several other minerals.
