Manufacturing Process Of Dicalcium Phosphate From Rock

Dicalcium phosphate

Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 4 2 – anion involves the removal of two protons from phosphoric acid, H 3 PO 4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate. Dicalcium phosphate is used as a food additive, it is found in some ...

Processing Phosphates for Use in Animal Feed

Phosphorus used in animal feed is first mined in the form of phosphate rock. In order to separate the phosphorus from the surrounding undesirable material, such as sand and clay, the phosphatebearing ore must go through a beneficiation process. As phosphate rock deposits vary considerably in their makeup, the beneficiation process can differ greatly from one deposit to the next.
