Process for making phosphoric acid - Davy McKee Corporation. In the process of this invention, the milling, e.g., grinding, of the slurry of the phosphate rock can be performed in conventional apparatus such as a ball mill, rod mill, or impact mill.
"Erosion-corrosion of 12 alloys in phosphoric acid waste water was studied by the Bureau of Mines. Tests were conducted on oblate spheroids or cylindrical specimens in 12- and 60-cm-diam ball mills by grinding phosphate rock in gypsum pond water with a starting ph of 1.6.
When phosphate rock is treated with sulphuric acid in sub stoichiometric quantity, normal superphosphate is formed. If more sulphuric acid is added, a mixture of phosphoric acid and gypsum (calcium sulphate) is obtained. After the gypsum is filtered out, the resultant phosphoric acid can be treated to recover uranium. The basic reaction is:
The phosphate rock slurry is then passed through a hydroclone circuit where the larger (heavier) particles are removed for recycling to the ball mill and the remaining lightweight particles in the rock slurry are processed by phosphoric acid plant.
The process involves acidifying phosphate rock with nitric acid to produce a mixture of phosphoric acid and calcium nitrate. Ca 3 (PO 4) 2 + 6 HNO 3 + 12 H 2 O → 2 H 3 PO 4 + 3 Ca(NO 3) 2 + 12 H 2 O. The mixture is cooled to below 0 °C, where the calcium nitrate crystallizes and can be separated from the phosphoric acid.

In a wet process facility, phosphoric acid is produced by reacting sulfuric acid (H2SO4) with naturally occurring phosphate rock. The phosphate rock is dried, crushed, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (CaSO4), commonly
