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

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
In a method of making dicalcium phosphate, the steps. which consist intreating phosphate rock with hydrochloric acid under heat, cooling the mixture to about 30 C., treating the liquid product...
A process is disclosed for the production of granulated dicalcium phosphate dihydrate from finegrained, powered dicalcium phosphate dihydrate, wherein 80 t0 95% of dicalcium phosphate dihydrate with a grain size of less than 120 m and 20 to 5% of calcium hydroxide with a grain size of less than 120 m are dry mixed and continuously sprayed and granulated in a fluidized bed with 20 to 50%
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 mixtures thereof.
The process has essentially three main steps: phosphate rock digestion, defluorination and neutralization. In the first step a phosphate rock slurry is batch digested with concentrated sulfuric acid in the presence of some additives that retain the fluorine in the solution, as well as enable the adequate growth of the calcium sulfate crystals and maximize the phosphate dissolution.
Dicalcium phosphate crystals are precipitated and after filtration and drying the resulting anhydrous dicalcium phosphate Process for the Manufacturing Bamni Proteins

Fluoride is removed in the preparation of dicalcium phosphate from wet process phosphoric acid by neutralizing the acid with an alkaline compound of calcium, lime or calcium carbonate, to a pH range ; removing the precipitate, which is mainly fluoride; and then neutralizing the residual acid to precipitate dicalcium phosphate.
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
