Processing Phosphates for Use in Animal Feed

As such, phosphorus is a key ingredient in animal feeds, namely Monocalcium Phosphate (MCP) and Dicalcium Phosphate (DCP). While only about 5% of global phosphate consumption goes toward animal feed production, the production of phosphate animal feeds plays a critical role in maintaining livestock health and overall food security.

DICALCIUM PHOSPHATE (DENTIFRICE GRADE)

Dicalcium phosphate is of great interest to tooth paste manufactures. It is used in toothpaste in its anhydrous variety. Although this product is not included in the accepted dental remedies, it is nevertheless used because of its considerably higher abrasive power compared to dehydrate. The demand of dicalcium phosphate is increasing day by day.
