The original source of most soil P is from the primary mineral apatite, or rock phosphate (RP).Apatite is a highly insoluble Ca-phosphate compound with the general formula of Ca 10 (PO 4) 6 X 2, where X is F − (fluoroapatite), OH − (hydroxyapatite), or Cl − (chloroapatite). In highly weathered, acidic soils, little or none of these apatite minerals remain in the soil.

The document discusses phosphate rock (phosphorite) which is a sedimentary rock containing high amounts of phosphate minerals. It forms in a variety of depositional environments, most commonly very shallow marine or low-energy settings. Phosphate is deposited as apatite, commonly fluorapatite. It can have igneous or sedimentary origins.

Phosphorite is a phosphate-rich sedimentary rock, that contains between 18% and 40% P₂O₅. The apatite in phosphorite is present as cryptocrystalline masses referred to as collophane. …

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 …

(U-Th)/He dating of apatite is also well established for use in determining thermal histories and other, less typical applications such as paleo-wildfire dating. Phosphorite is a phosphate-rich sedimentary rock, that contains between 18% and 40% P₂O₅. The apatite in phosphorite is present as cryptocrystalline masses referred to as collophane.

Neon Blue Apatite is a captivating gemstone known for its vibrant blue hue that can range from light to deep electric blue. It belongs to the Apatite family, which is a group of phosphate minerals commonly found in igneous and metamorphic rocks. The chemical composition of Apatite includes calcium phosphate combined with fluoride, chloride, or hydroxide.

Apatite, like other phosphate ores, is the main raw material for the production of phosphoric acid. So, it is the main element for the production of phosphate fertilizers.

APATITE AND ROCK PHOSPHATE 1 Apatite and Rock Phosphate A patite is a group of phosphate minerals and named by German Geologist Abraham Werner in 1786. It is the most abundant crystalline phosphate mineral found as an accessory mineral in practically all kinds of igneous rocks. Sometimes, it is concentrated in pegmatites, metallic veins and

Phosphate rock is an important mineral commodity used in the chemical industry and production of food. The first section of ninth chapter of this book introduces utilization of apatite ores for manufacturing of phosphorus. The second part deals with production of phosphoric acid via wet and thermal process and utilization of byproducts such as …

Its main constituent is apatite, a calcium phosphate mineral primarily extracted from sedimentary marine deposits, with a small amount obtained from igneous sources. ... When phosphate rock is added to soil, it slowly dissolves to gradually release nutrients, but the rate of dissolution may be too slow to support healthy plant growth in some ...

Apatite [Ca 5 (PO 4,CO 3) 3 (OH,F,Cl)] is the most abundant phosphate mineral, which accounts for more than 95% of all phosphorus in the Earth's crust and is found as an accessory mineral in most rock types 1. A rock may be best defined as any mineral or aggregate of minerals that forms an essential part of the Earth [].Apatite is found in all classes of rock: …

Phosphate ore (apatite) is converted into fertilizer with sulfuric acid and phosphogypsum is a by-product of this process. Approximately 5 tons per ton of P 2 O 5 is produced. Rock phosphate is a naturally occurring source for P 2 O 5. Production of rock phosphate in India is shown in Fig. 14.3.

Apatite (Fig. 1.12) is a group of natural calcium mineral±fluorine and chlorine (Ca 5 (PO 4) 3 (F, Cl, OH)). The mineral primarily occurs as phosphate rock.
