· The production process include the neutralization of calcium hydroxide by phosphoric acid that gives Dicalcium phosphate as a dehydrate precipitate. When its reaction is done at or around 60°C, the anhydrous form is produced. H 3 PO 4 + Ca(OH) 2 → CaHPO 4. The degradation of this final product can form hydroxyapatite. Therefore, in order to avoid the degradation, sodium pyrophosphate .
Foodgrade phosphates are used in the production of foods to function as buffers, sequestrants, acidulants, bases, flavors, cryoprotectants, gel accelerants, dispersants, nutrients, precipitants, and as freeflow (anticaking) or ion exchange agents. The actions of phosphates affect the chemical leavening of cakes, cookies, pancakes, muffins, and doughnuts; the even melt of processed cheese ...
· The precipitation kinetics of calcium phosphates, namely, hydroxyapatite (HAP), dicalcium phosphate dihydrate (DCPD), dicalcium phosphate anhydrous (DCPA), and monocalcium phosphate monohydrate (MCPM), were studied at 30°C by mixing calcium hydroxide, water, and phosphoric acid. The studied mixture was selected according to the stability domain of different calcium phosphates .

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 .

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 .

The studied mixture was selected according to the .
An investigation was undertaken to develop a process for producing dicalcium phosphate by direct acidulation of phosphate rock. In general, when phosphate rock is treated with sulfuric acid, monocalcium phosphate or phosphoric acid is formed. If less sulfuric acid is used, dicalcium phosphate should be formed theoretically, however only monocalcium phosphate .

A process as claimed in claim 1, wherein after separation, the leach liquor is treated with sulphuric acid during or after the leaching step to bring about the precipitation, as gypsum, of calcium in excess of that required to meet the Ca/P ratio of dicalcium phosphate, the gypsum is separated and the liquor is distilled at 80°100° C. to precipitate dicalcium phosphate.
dicalcium phosphate and tricalcium phosphate of animal origin. (Mineralderived versions are permitted for all livestock and are the most commonly used – feed labels not specifying 'animal origin' can be taken to be of mineral origin); processed animal protein (PAP) derived from nonruminants (including insect PAP) may be used for feeding aquaculture animals. Aquaculture .

The developed process achieves around 70% phosphorus recovery as an industrialgrade (19 wt% P) dicalcium phosphate dihydrate product with minimal iron, magnesium, and aluminum contamination, while also producing valueadded calcium sulfate dihydrate (gypsum) and iron/magnesium byproducts. This process enables economical and sustainable recovery of .
A process for producing calcium hydrogen phosphate dihydrate is provided by which it is possible to obtain calcium hydrogen phosphate dihydrate that has high particlesurface activity and is hence useful as a fluorine insolubilizer, etc., without necessitating any treatment. Also provided is a fluorine insolubilizer. A calcium salt was reacted with phosphoric acid and/or a .

human induced erosion processes, phosphates from these rock deposits are washed into rivers, and eventually to the oceans, where they form shallow and deep ocean phosphate rock deposits. Animal bones and teeth are made up of calcium phosphate and contribute to the cycle. Phosphate levels have risen due to: Detergent Contamination – phosphate is used in .
Animal feed grade phosphates such as monocalcium phosphate, dicalcium phosphate or mixtures thereof are produced by direct reaction between phosphoric acid and Cacontaining materials. A finely ground, preheated calcium carbonate suspension is brought to react with a suitable quantity of preheated phosphoric acid by introducing the reactants into a short, tubular .
