This report presents the economics of Phosphoric Acid production from phosphate rock in the United States via a dihydrate wet process. In this process, phosphate rock is digested with sulfuric acid to producing Phosphoric Acid with the precipitation of calcium sulfate dihydrate. Phosphoric acid is further concentrated to a final product containing 54 wt% of P2O5.
This report presents the economics of Phosphoric Acid production from phosphate rock in the United States via a hemidihydrate wet process with intermediate separation of the hemihydrate. The Phosphoric acid produced is subjected to a further concentration step to obtain a final product containing 54 wt% of P2O5.
This report presents the economics of Phosphoric Acid production from phosphate rock in the United States via a hemihydrate wet process. In this process, phosphate rock digestion with sulfuric acid proceeds in two distinct zones, with the precipitation of calcium sulfate hemihydrate. The Phosphoric acid produced is subjected to a further concentration step to obtain a final product containing 54 wt% of P2O5.
This report presents the economics of Phosphoric Acid production from phosphate rock in the United States via a hydrochloric acid route similar to the one developed by the Israel Mining Industry (IMI). In this process, phosphate rock is dissolved by hydrochloric acid, resulting in an aqueous solution of calcium chloride and Phosphoric Acid. The Phosphoric Acid is separated from the solution via solvent extraction and further concentrated to obtain a final product containing 69 wt% of P2O5.
This report presents the economics of an integrated process for the production of Phosphoric Acid from phosphate rock involving: (1) the production of elemental phosphorus from phosphate rock; and (2) the production of Phosphoric Acid from elemental phosphorus via a thermal process. The final product obtained in this process is Phosphoric Acid containing 54 wt% of P2O5. The economic analysis performed is based on a plant constructed in the United States.
This report presents the economics of Phosphoric Acid production from phosphorus in the United States via a typical thermal process. In this process, elemental phosphorus is burned in a combustion chamber forming phosphorus pentoxide, which is then hydrated to produce Phosphoric Acid containing 54 wt% of P2O5.
