Animal Feed Supplements: Defluorinated phosphate rock or phosphoric acid are used to make animal feed supplements. PCS, in north Florida, and Mosaic in central Florida produce animal feed supplements. One way to produce the feed is to combine phosphate rock with a small amount of phosphoric acid, sodium carbonate and then calcine.
• Dicalcium phosphate is one of the mineral phosphorous sources that is commonly used in organic diets. • Dicalcium phosphate was produced in the Serrana plant in Cajati, Brazil by mixing powdered limestone with defluorinated 5052% phosphoric acid and depositing it on a slow moving covered conveyor belt (den). The production was 165,000 mtpy. • The share of dicalcium phosphate precipitated from bones .
