apatite can be divided into fluorapatite, chlorapatite and hydroxyapatite according to the type of additional anion. Sometimes the additional anion is (C03)2-, which is called carbon apatite, among them, fluorapatite is the most common. Hexagonal crystal system, the crystal is often hexagonal columnar, aggregate block, granular or tuberculosis, etc. Due to different colors containing impurities, there are gray-green, light green, blue-green, blue-purple, light red, red-brown, yellow, etc., pure colorless and transparent, with light green and gray-green more common. Glass gloss, the fracture was oil gloss, White Stripes. Hardness 5, density 3. 18~3.41g/cm3. It is insoluble in water and emits phosphorescence after heating. When rubbing, it emits a burning smell like fur. Apatite is a phosphate mineral widely distributed in the Earth's crust, which can be formed in endogenesis, Exogenesis and metamorphism. About 95% of the phosphorus in nature is concentrated in apatite.
mining method and process flow are the same as that of phosphorite. Due to the coarse particle size and good floatability of the phosphorus minerals in the apatite ore of magmatic rock type and the phosphate limestone ore of metamorphic rock type, the phosphorus minerals can be directly obtained by the positive flotation method, in addition, the iron minerals in the ore can be recovered by phosphorus separation method. The general beneficiation process is the same as that of phosphorite. The Maying phosphate mine in Chengde city, Hebei province is a magmatic type apatite ore, and its flotation process is one roughing, one sweeping and two selecting; The flotation froth product is a phosphate concentrate; The medium ore is a vanadium-iron concentrate obtained by magnetic separation.
see phosphorite ". In addition, fluorapatite 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. Phosphate rock associated with vanadium, titanium, iron, rare earth, strontium, uranium, iodine, fluorine and other elements reached a certain content can be comprehensive recycling.
Same as phosphorite ".

Hydroxyapatite | Hydroxyapatite, also known as hydroxyapatite, is the natural mineralization of calcium apatite (Ca5(PO4)3(OH)). Its molecular formula is Ca5(PO4)3(OH), but it is often written as Ca10(PO4)6(OH)2 to represent the crystal structure composed of two molecules. Hydroxyapatite is a pure positive end element containing hydroxide in apatite. OH-ions can be replaced by fluoride ions, chloride ions or carbonate ions to form fluorapatite or chlorapatite. Hydroxyapatite, abbreviated as HAP, is the most widely used calcium phosphate crystalline phase. Calcium phosphate is the main mineral component of vertebrate bones and teeth. Among calcium phosphate salts, hydroxyapatite is the most thermodynamically stable crystalline phase of calcium phosphate in body fluids, and is most similar to the mineral parts of human bones and teeth. The ratio of calcium and phosphorus in hydroxyapatite is affected by the synthesis mode, and the composition is more complicated if the ratio of calcium to phosphorus is not fixed. |
Use | Used as fertilizer and feed additive Hydroxyapatite has a wide range of applications in the following fields due to its unique physical and chemical structure:(1) Application in sewage treatment;(2) Application in remediation of contaminated soil;(3) Application in medicine;(4) Other applications. Purify protein, separate single-stranded RNA from double-stranded RNA, and purify DNA. |
production method | 1. fresh animal bones are cleaned and removed, steamed to remove bone glue fat, and then dried and crushed to prepare bone meal. |
