History of Phosphate Fertilizer Production

Sulfuric Acid: This acid is produced at phosphate plants for use in reacting with phosphate rock to produce phosphoric acid. The heat generated off sulfuric acid production is used to power phosphate manufacturing plants and extra energy is often sold back to the area electric grid. Some sulfuric acid may be sold separately as a product.

Phosphoric acid | H3PO4 - PubChem

Phosphate is a salt of phosphoric acid. In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid.Organic phosphates are important in biochemistry, biogeochemistry and ecology. Phosphate (Pi) is an essential component of life. In biological systems, phosphorus is found as a free phosphate ion in solution and is called inorganic phosphate, to distinguish it from ...

Phosphoric acid - Essential Chemical Industry

Phosphorus is an essential plant nutrient and is taken up by plant roots, usually as the dihydrogenphosphate ion, H 2 PO 4-, derived from phosphoric acid, H 3 PO 4.The manufacture of fertilizers that are used to rectify phosphorus deficiencies in soils depends on the availability of supplies of phosphoric acid.

The Center for Land Use Interpretation

The Don Plant is the largest of four fertilizer plants operated by J. R. Simplot. Another is an isolated facility outside of Rock Springs, Wyoming, where the company makes monoammonium phosphate (MAP), as well as phosphoric acid. The Rock Springs plant was built by Chevron in the mid-1980s, and was taken over by Simplot in 2003.

Phosphate Fertilizer Production Plants and Phosphoric Acid ...

Phosphoric acid or phosphate cannot function as phosphorous acid or phosphite and vice versa. Since phosphites are systemic and very stable in plants, they should not be applied frequently. To help delay the development of phosphite-resistant oomycetes, care should be taken to alternate or mix phosphite with other effective compounds.


5. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL hydrofluoric acid, which was 350,000 metric tons in 2001, is expected to increase to 364,000 metric tons in 2005 (CMR 2002). Sodium fluoride is manufactured by the reaction of hydrofluoric acid with sodium carbonate or sodium hydroxide. The salt is centrifuged and dried (Mueller 1994).
