dicalcium-phosphates-process, technology, applications

Dicalcium phosphate crystals are precipitated and after filtration and drying the resulting product is a very pure crystalline dihydrate dicalcium phosphate that is sold as Aliphos® Dical. Dicalcium phosphate is obtained from degreased bones which are demineralised by hydrochloric acid treatment and precipitated by a saturated lime solution

processes for the manufacture of feed-gradedicalcium

The process comprises the reaction of an excess of phosphate rock with aqueous solutions of a mineral acid selected from hydrochloric acid, phosphoric acid and nitric acid, characterized by the fact that the free acidity of the dissolution liquor does not exceed 60% and that in the clear solution feed grade dicalcium phosphate is precipitated with calcium hydroxide, calcium carbonate or mixtures thereof

This invention relates to the preparation of feed grade dicalcium phosphate from a source containing monocalcium phosphate such as super phosphate, concentrated super phosphate and the like. The first step consists of leaching water soluble mono calcium phosphate therefrom with water or recycle wash water from one of the subsequent steps
