ROCK PHOSPHATE - ChemicalBook

Rock phosphate is a natural mineral found as a geological deposit on a large scale in the form of sedimentary rocks containing various amounts of calcium phosphates. Once ground, it is used as a phosphatic fertilizer, called phosphorite or mineral phosphate, or as a primary source of phosphorus. Rock phosphate deposits are found in many ...

phosphate [fos´fāt] any salt or ester of phosphoric acid. adj., adj phosphat´ic. Phosphates are widely distributed in the body, the largest amounts being in the bones and teeth. They are continually excreted in the urine and feces and must be replaced in the diet. Inorganic phosphates function as buffer salts to maintain the acid-base balance in ...

phosphorite Definition, Formation, Uses Britannica

phosphorite, also called phosphate rock, rock with a high concentration of phosphates in nodular or compact masses. The phosphates may be derived from a variety of sources, including marine invertebrates that secrete shells of calcium phosphate, and the bones and excrement of vertebrates.. The thickest deposits of phosphorite form in areas characterized by carbonaceous shale and chert.

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.

2010-8-9  2 The term "phosphate rock" is loosely applied to rocks of any origin that contain more than about 20 percent P2Os. The term "phosphorite" is equivalent in meaning, but is commonly applied only to phosphate rocks of marine origin. "Guano" is the term applied to accumulations of animal excrement, altered to various degrees through hydration ...

Phosphate Formula: Definition, Structure, Types, Uses

2021-7-22  Phosphate Ion (PO43-) A phosphate ion is formed when three protons are removed from phosphoric acid (H3PO4). It is a polyatomic ion with the formula PO43 −. It is also called a phosphate group. In this ion, the central phosphorous ion is surrounded by four oxygen atoms. Hence, it has a tetrahedral shape.

Phosphorus Fertilizers - an overview ScienceDirect Topics

Phosphorus fertilizers are manufactured from rock phosphate (Figure 2.2 ), but rock phosphate itself seldom is used directly as a fertilizer because of its low availability of phosphorus and transport cost. Instead, finely ground rock phosphate is treated with sulfuric acid to yield monocalcium phosphate monohydrate and is known as superphosphate.

What is Phosphate Fertilizer? (with pictures)

Phosphate fertilizer in its liquid form can be easily applied to fields and crops. The process by which phosphate rock is converted to phosphate fertilizer involves treatment with sulfuric acid; the result is often called "super phosphate."This treatment with sulfuric acid draws the phosphates from the raw ore and creates a water soluble form.
