Dicalcium phosphate Wikipedia

Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. 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. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate. Dicalcium phosphate is used as a stone additive, it is found in some

DCP DiCalcium Phosphate poultry Feed Grade-DCP18%

Dicalcium Phosphate poultry feed grade is an organic weight loss plan of mineral phosphate due to the fact bones meal and meat usually are not allowed in poultry industries. Dicalcium Phosphate makes use of as nutritional complement diets with feed formulations. Most important part of poultry birds required is phosphate and calcium traditional feedstuffs of their diets.

Processes for the manufacture of feed-grade dicalcium

26/10/1976· The combined process of DCP manufacture and phosphoric acid production minimizes any losses of P 2 O 5 normally encountered in the attack on rock phosphate by a mineral acid in the DCP manufacture since, according to the present invention, the reaction system for the manufacture of DCP implies an excess of phosphate rock in which almost the entire P 2 O 5 content is solubilized in

Radionuclide fluxes at a plant manufacturing dicalcium

We have studied a phosphate rock plant which produces dicalcium phosphate (DCP), used as a source of calcium and phosphorus for domestic animals. A by-product in the manufacturing process is calcium chloride which is used in the oil industry, the stone industry and as road-salt. The objectives of our study were to describe the fluxes of radionuclides from the 238 U decay series and to estimate

Dose assessment to workers in a dicalcium phosphate

The production of dicalcium phosphate (DCP) uses phosphate rock (PR) as a raw material. Sedimentary phosphate rocks are enriched with relevant concentrations of natural radionuclides from the 238 U decay chain (around 10 3 Bq·kg −1), leading to the need of controlling potential exposures to radiation of workers and members of the public in accordance with IAEA safety standards.
