The Versatile Apatite Mineral Group - Advancing

20/05/2014  The word apatite is derived from the Greek word for deceit, “apate” because apatite can be mistaken for many other minerals. It is usually green, but can also be blue, yellow, purple, or brown. Apatite is the main source of phosphorous, an important nutrient required by plants. As such, apatite is the key ingredient in phosphate

Mining and Beneficiation – Phosphate Research Network

Apatite is the main mineral of phosphate ore. The apatite group includes Fluorapatite, Chlorapatite, and Hydroxyapatite. But, the major mineral, especially in sedimentary phosphate rock is fluorapatite. Beside apatite, there are many other minerals and impurities. Many impurities are inside apatite mineral, but some of them are outside the apatite mineral. The major part of exogangue ...

Apatite: From Crystals to Phosphate Rock Rock Gem

High-grade phosphate rock, the only commercial source of phosphorus, contains at least 10 percent elemental phosphorus in the form of apatite. As the base of the 25-billion-dollar-per-year global mining industry, more than 255 million tonnes of phosphate rock are mined annually from open pits. After concentration, an acid treatment converts the apatite into a hydrated calcium phosphate called ...

Mining Funda: Apatite, Phosphorite and Phosphate Rock

Phosphate rock and phosphorite are names used for sedimentary rocks that contain at least 15% to 20% phosphate on the basis of weight. The phosphorous content in these rocks is mainly derived from the presence of apatite minerals. Determining which apatite-group minerals are contained in the rock cannot be determined without laboratory testing because their particle sizes are so small.

Mineral Resource of the Month: Phosphate Rock

28/01/2015  The first documented phosphate rock mining took place in England in 1847, using picks and shovels. Mining first began in the United States in 1867 in South Carolina. Phosphate rock was discovered in central Florida in the 1880s, and because of the extensive, high-quality deposits and lower mining cost, it quickly became the leading phosphate-producing state. Currently, phosphate rock is
