production of dicalcium phosphate with hydrochloric acid flowchart
Food and feed phosphates such as MCP, DCP and TCP - Ingetecsa
The acid and limestone react together to produce MCP, DCP and (rarely) TCP. DCP production is also possible directly as a precipitate from attacking the phosphate rock with hydrochloric acid (substitution reaction). This niche process uses for instance waste hydrochloric acid from electrochemical plants / water dissociation.

Dicalcium Phosphate From Rock Phosphate
Dicalcium Phosphate From Rock Phosphate Dicalcium phosphate, also known as calcium monohydrogen phosphate, is a dibasic calcium phosphate. •Dicalcium phosphate is usually found as the dihydrate, but it can be thermally converted to the anhydrous form. It is practically insoluble in water, with a solubility of 0.02 g per 100 mL at 25 °C.
