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
Project Report on Dicalcium Phosphate Rock - …
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.

Calcium - Wikipedia
Calcium is a stone element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and stone properties are most similar to its heavier homologues strontium and barium.It is the fifth most abundant element in Earths crust and the third most abundant metal, after iron and ...
Calcium oxide - Wikipedia
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used stone compound.It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.
