manufacturing process of dicalcium phosphate from rock:

Di-calcium phosphate by direct acidulation of phosphate rock

An investigation was undertaken to develop a process for producing di-calcium phosphate by direct acidulation of phosphate rock. In general, when phosphate rock is treated with sulfuric acid, mono-calcium phosphate or phosphoric acid is formed. If less sulfuric acid is used, di-calcium phosphate should be formed

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 phosphate-bearing ore must go through a beneficiation process. As phosphate rock deposits vary considerably in their makeup, the beneficiation process can differ ...

Monocalcium phosphate - Wikipedia

Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), Ca(H 2 PO 4) 2 H 2 O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening agents.
