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 ...

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 potassium sulfate ...

process to manufacture phosphoric acid from dicalcium ...

Process for producing phosphoric acid and dicalcium . The manufacture of phosphoric acid is conventionally performed on a commercial scale by either the wet process or the thermal process. In the wet process, phosphate rock is treated with sulfuric acid to produce weak aqueous phosphoric acid (20 - 30% P.sub.2 O.sub.5) and calcium sulfate.
