manufacturing process of dicalcium phosphate from rock
The process comprises three main steps: solubilization of the phosphate rock concentrate with sulfuric acid, defluorination of the phosphoric acid solution with potassium sulfate and neutralization of the phosphoric acid solution with calcium hydroxide
The combined process of DCP manufacture and phosphoric acid production minimizes any losses of P 2 O 5 normally encountered in the attack on rock phosphate by a mineral acid in the DCP manufacture since, according to the present invention, the reaction system for the manufacture of DCP implies an excess of phosphate rock in which almost the entire P 2 O 5 content is solubilized in step (d)
