  • Production of defluorinated dicalcium phosphate from

    A new process to produce defluorinated dicalcium phosphate (DCP) using phosphate rock concentrate has been developed. This new process has as main characteristic the low concentration of P 2 O 5 in the liquid phase. The process comprises three main steps solubilization of the phosphate rock concentrate with sulfuric acid defluorination of the phosphoric acid solution with potassium

  • Production of dicalcium phosphate or monocalcium

    Production of dicalcium phosphate or monocalcium phosphate from calcium phosphate . United States Patent 6183712 . Abstract A method of producing dicalcium phosphate from calcium phosphate includes reacting the calcium phosphate with a mineral acid such as sulphuric acid to produce a calcium salt and phosphoric acid. The calcium salt may then be hydrolyzed to form a
