APATITE

Apatite, whose chemical formula is Ca₅(PO₄)₃F, is a mineral of importance with CAS number 64476-38-6. The mineral has a molecular weight of 504.3 g/mol and an exact mass of 503.671619 g/mol. The color of Apatite varies greatly, mainly depending on the type and amount of impurities contained in it, resulting in a rich variety of colors. Its surface area (PSA) is 259 A ², which makes it highly reactive and has the potential for a wide range of applications. In terms of mining, the mining methods of Apatite are the same as those of phosphate rock, and the positive flotation method is usually used to directly obtain phosphate minerals. The advantage of this method lies in the good flotation ability of Apatite. Its beneficiation process is similar to that of phosphate rock, especially in Maying phosphate rock in Chengde City, Hebei Province, which is a magmatic apatite mine. Here, the flotation process of 1 roughing, 1 sweeping and 2 separation was adopted to successfully obtain phosphate concentrate and iron vanadium concentrate. In addition to its application in phosphate mining, fluoropapatite crystals are widely used in phosphate glass lasers because of their excellent laser emission characteristics. In addition, Apatite can also be used as an ion exchanger for isotope separation. With the development of recovery technology of vanadium, titanium, iron, rare earth, strontium, uranium, iodine, fluorine and other elements in ores, the potential of Apatite in the comprehensive utilization of resources is attracting more and more attention. The recycling of these elements not only contributes to the sustainable use of resources, but also opens new frontiers for the application of Apatite.

The mining method and technological process are the same as phosphorite. Because the phosphate minerals in magmatic rock type apatite mines and metamorphic rock type apatite mines are coarser and have good floatability, the phosphate minerals can be directly obtained by the positive flotation method, and the phosphorus mineral can be recovered by the phosphorus separation method. Iron minerals in ore. The general beneficiation process is the same as that of phosphorite. The Maying Phosphate Mine in Chengde City, Hebei Province is a magmatic rock type apatite mine. Its flotation process is one roughing, one sweeping and two beneficiation; the flotation foam product is the phosphate concentrate; Obtain vanadium iron concentrate.

See ~~"Phosphate Rock~~". In addition, fluoroapatite crystals are ideal laser emitting materials and have been used in phosphate glass lasers; they can also be used as ion exchangers for isotope separation. The elements such as vanadium, titanium, iron, rare earth, strontium, uranium, iodine, and fluorine in phosphate rock can be recycled comprehensively when they reach a certain content.
