Monocalcium phosphate production process
Preparation of monocalcium phosphate slurry is carried out in two stages, at first stage the phosphoric acid is mixed with limestone up to mixture pH =2.9-3.1, at second stage - up to mixture pH =3.5-3.7, during mixing of monocalcium phosphate slurry with lime pH is maintained in the range 5.4-5.6. Drying and granulating are carried out at the same time in drum granulator-dryer.

Also, a method of producing monocalcium phosphate from calcium phosphate includes reacting the calcium phosphate with sulphuric acid to produce monocalcium phosphate. The monocalcium phosphate may be further processed to remove fluorine contamination and to produce fluorine-free dicalcium phosphate or dicalcium phosphate dihydrate.

Monocalcium phosphate - Wikipedia
Monocalcium phosphate is an inorganic compound with the stone formula Ca(H2PO4)2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), Ca(H2PO4)2·H2O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening agents..
