The invention relates to a combined process for the manufacture of feed grade dicalcium phosphate and pure phosphoric acid. The process comprises the reaction of an excess of phosphate rock with aqueous solutions of a mineral acid selected from hydrochloric acid, phosphoric acid and nitric acid, characterized by the fact that the free acidity of the dissolution liquor does not exceed 60% and ...
Phosphogypsum is the principal byproduct produced by the wet processes involved in the manufacture of phosphoric acid. The main component of phosphate rock is FAp, and so fluorides, such as sodium fluoride (NaF), calcium fluoride (CaF 2), and sodium hexafluorosilicate (Na 2 SiF 6), 6 are contained as impurities in phosphogypsum. In Japan ...

Jul 26, 2016· Process of making dicalcium phosphate process fluoride phosphoric acid process for making dicalcium phosphate from dicalcium phosphate manufacturing process using rock . dicalcium phosphate ...
A new process for the production of defluorinated dicalcium phosphate using phosphate rock was developed. This new process has the main characteristic of being clean, without the production of any liquid waste. The process has essentially three main steps: phosphate rock .
Feb 06, 2001· A method of producing dicalcium phosphate from calcium phosphate includes reacting the calcium phosphate with a mineral acid such as sulphuric acid to produce a calcium salt and phosphoric acid. The calcium salt may then be hydrolyzed to form a calcium alkali which may then be reacted with the phosphoric acid to produce dicalcium phosphate.
Acid produced by the ''wet'' route is less pure but is used in the manufacture of fertilizers. (a) Wet process. Phosphoric acid is produced from fluorapatite, known as phosphate rock, 3Ca 3 (PO 4) 2, by the addition of concentrated (93%) sulfuric acid in a series of wellstirred reactors. This results in phosphoric acid and calcium sulfate ...
Monocalcium phosphate, phosphoric acid and/or potassium phosphate containing fertilizers are produced in a process involving acidulation of phosphate rock with phophoric acid in the presence of added silicon dioxide and potassium ion whereby fluorides contained in the rock are converted to K 2 SiF 6, wherein monocalcium phosphate dissolved in phosphoric acid is formed during acidulation.
This invention relates to the preparation of feed grade dicalcium phosphate from a source containing monocalcium phosphate such as super phosphate, concentrated super phosphate and the like. The first step consists of leaching water soluble mono calcium phosphate therefrom with water or recycle wash water from one of the subsequent steps.
Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMPA" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCPM"), Ca(H 2 PO 4) 2 ·H 2 O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening agents.

us patent for manufacturing process of dicalcium phosphate. A process is described for highly efficient recovery of phosphate values from a wide range of phosphate rock including low grade phosphate rock material by leaching with a dilute sulfuric acid and precipitating phosphate values as dicalcium phosphate.
Dicalcium Phosphate is a calcium phosphate salt of phosphoric acid with the formula: CaHPO is a common additive/ ingredient of products primarily involved in the agriculture (feed ingredient), food, personal care, and medicinal (pharmaceutical additive) industries.

Cited by: 3; USA Processes for the manufacture of feedgrade. The invention relates to a combined process for the manufacture of feed grade dicalcium phosphate and pure phosphoric acid.
phosphate rock with sulfuric acid or phosphoric acid. The acidulation process converts the highly insoluble phosphate in mineral apatite into forms which are available to plants, such as monocalcium phosphate an£^ dicalcium phosphate CaHPO^. "When phosphate . Learn More; dicalcium phosphate process fluoride phosphoric acid
Dicalcium phosphate is usually prepared by the action of a sulfuric or phosphoric acid upon phosphate rock or other insoluble calcium phosphates, and also by the double decomposition of dibasic sodium phosphate with calcium chlorid. The''present method is simpler than either of the above, and is relatively inexpensive.
Mono and dicalcium phosphate. KEMWorks offers technology for the production of minigranular animal feed ingredients. Animal feed products require a P/F ratio of at least 100:1 so phosphoric acid used to produce mono and dicalcium phosphate (MCP/DCP) must usually be defluorinated.
Example of phosphoric acid production. Wet process phosphoric acid is prepared by adding sulfuric acid (H 2 SO 4) to apatite or tricalcium phosphate rock resulting in the following reaction: . 3 H 2 SO 4 + Ca 3 (PO 4) 2 + 6 H 2 O ↔ 2 H 3 PO 4 + 3 CaSO 4 •2H 2 O . Wetprocess acid has to be purified by removing fluorine and other undesirable elements to produce feedgrade phosphoric acid.
Full Text: This invention relates to a process for the manufacture of feed grade dicalcium phosphate. Dicalcium phosphate known, as DCP is a commonly used animal feed supplement and it is desirable to obtain dicalcium phosphate free of contaminants, particularly fluoride containing compounds.
Dicalcium phosphate shows the most commonly used production method is known as the "wet acid" route in which rock phosphate is reacted with sulphuric acid to produce phosphoric acid. After concentration and purification to reduce the level of undesirable elements, this phosphoric acid is
