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.
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 reacted with a calcium source such as quick lime or limestone to produce dicalcium phosphate.
May 01, 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
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 . Contact Supplier

Apr 01, 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.
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
In a method of making di-calcium phosphate, the steps. which consist intreating phosphate rock with hydrochloric acid under heat, cooling the mixture to about 30 C., treating the liquid product...

As a Rock Phosphate Wholesale Manufacturer, we feel that the production process makes a big difference. The most common form of manufacturing is called the ‘wet acid’ method. In this method, the rock phosphate is made to react with concentrated Sulphuric Acid. This releases phosphoric acid, which is further processed and then cleansed.
It also relates to methods for the manufacture of monocalcium phosphate fertilizer, edible monocalcium phosphate and edible dicalcium phosphates. BACKGROUND OF THE INVENTION. Tricalcium orthophosphate, Ca 3 (PO 4) 2, commonly known as calcium phosphate, occurs in nature as rock phosphate ore, for example and is used as such as a source of

This paper presents results laboratory experiments to test a new process for manufacture of dicalcium phosphate. The process is based on the nitric acidulation of phosphate rock concentrate, followed by neutralization of the extract liquor with calcium carbonate. The precipitated dicalcium phosphate is then separated from calcium nitrate solution by filtration. The dicalcium phosphate thus
