The "di" prefix in the common name arises because the formation of the HPO 4 2– anion involves the removal of two protons from phosphoric acid, H 3 PO 4. Dibasic calcium phosphate is produced by the neutralization of calcium hydroxide with phosphoric acid, which precipitates the dihydrate as a solid.
Fluosilicic acid is reacted with phosphate rock in order to produce wet process phosphoric acid and calcium fluoride which is later reacted with sulfuric acid to produce hydrogen fluoride and calcium sulfate. The hydrogen fluoride is then stripped from the phosphoric acid and recovered as either anhydrous hydrogen fluoride or concentrated hydrofluoric acid or reacted with aluminum trihydrate ...

Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), 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.

Samples of Ca(H 2 PO 4) 2 tends to convert to dicalcium phosphate: Ca(H 2 PO 4) 2 → Ca(HPO 4) + H 3 PO 4 Applications Use in fertilizers. Superphosphate fertilizers are produced by treatment of "phosphate rock" with acids. Using phosphoric acid, fluorapatite is converted to Ca(H 2 PO 4) 2: Ca 5 (PO 4) 3 F + 7 H 3 PO 4 → 5 Ca(H 2 PO 4) 2 + HF
A Phosphate is a chemical derivative of phosphoric acid. For this purpose, phosphate minerals are converted to phosphoric acid. An inorganic example of a triprotic acid is orthophosphoric acid (H 3 PO 4 ), usually just called phosphoric acid.
The diluted sulphuric acid stream resulting from this process can be preconcentrated and recycled to the phosphoric acid plant or used in production of fertilizers like single superphosphate SSP, dicalcium phosphate DCP, ammonium sulphate AS, etc or concentrated and recycled to …

Dicalcium phosphate is the calcium phosphate with the formula CaHPO4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO42– anion involves the removal of two protons from phosphoric acid, H3PO4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate.
acid, allows it to be stripped of fluorides in the evapora- tor to a P/F ratio of 100 or higher, Acid used in animal feed products must have a minimum P/F of 100. If there is fluoride in the limestone used for feed-grade dicalcium phosphate, the acid P/P must be about 125. Fifty-four …
The aqueous phase, after removal of the calcium fluoride, is treated with an additional 10% milk of lime to adjust the pH to between 4.7 and 5 to precipitate out dicalcium phosphate. Dicalcium phosphate is separated from the aqueous phase and is upgraded in a conventional dicalcium phosphate plant or cycled to a conventional wet acid phosphoric ...
