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.
L'invention concerne un procédé de fabrication d'hydrogénophosphate de calcium à partir de phosphate de calcium. Ce procédé consiste d'une part à faire réagir le phosphate de calcium avec un acide minéral afin de produire un sel de calcium et un acide phosphorique, d'autre part à hydrolyser le sel de calcium afin de produire un alcali de calcium et enfin à faire réagir l'alcali de calcium avec l'acide phosphorique afin de produire de l'hydrogénophosphate de calcium. L'invention porte également sur des procédés de fabrication d'engrais de phosphate monocalcique et de phosphates monocalciques et dicalciques comestibles à partir de phosphate de calcium.
