dicalcium phosphate production process,

01/04/1994 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 digestion, defluorination and neutralization. In the first step a phosphate rock slurry is batch digested . Cited

Dicalcium Phosphate From Rock Phosphate

Dicalcium Phosphate From Rock Phosphate Dicalcium phosphate, also known as calcium monohydrogen phosphate, is a dibasic calcium phosphate. •Dicalcium phosphate is usually found as the dihydrate, but it can be thermally converted to the anhydrous form. It is practically insoluble in water, with a solubility of 0.02 g per 100 mL at 25 °C. •Dicalciumphosphate (CaHPO4.2H2O) is a chemical

Di-calcium phosphate by direct acidulation of phosphate rock

An investigation was undertaken to develop a process for producing di-calcium phosphate by direct acidulation of phosphate rock. In general, when phosphate rock is treated with sulfuric acid, mono-calcium phosphate or phosphoric acid is formed. If less sulfuric acid is used, di-calcium phosphate should be formed

Production of defluorinated dicalcium phosphate from

01/05/1997· A new process to produce defluorinated dicalcium phosphate (DCP) using phosphate rock concentrate has been developed. This new process has as main characteristic the low concentration of P 2 O 5 in the liquid phase. The process comprises three main steps: solubilization of the phosphate rock concentrate with sulfuric acid, defluorination of the phosphoric acid solution with

patent of dicalcium phosphate from rock phosphate. Processes for the manufacture of feedgrade dicalcium . Oct 26 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

Processes for the manufacture of feed-grade dicalcium

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 that in the clear solution feed grade dicalcium phosphate is precipitated with calcium hydroxide, calcium carbonate or

Dicalcium-Phosphates- Process, Technology, Applications

Dicalcium phosphate crystals are precipitated and after filtration and drying the resulting product is a very pure crystalline dihydrate dicalcium phosphate that is sold as Aliphos® Dical. Dicalcium phosphate is obtained from degreased bones which are demineralised by hydrochloric acid treatment and precipitated by a saturated lime solution.
