A method of producing dicalcium phosphate from calcium phosphate includes reacting the calcium phosphate with a mineral acid such as sulphuric acid to produce a calcium salt and phosphoric acid. The calcium salt may then be hydrolyzed to form a calcium alkali which may then be reacted with the phosphoric acid to produce dicalcium phosphate. 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.
