Phosphate nutrients play an essential role in meeting the needs of a growing world. Here in Florida, 90 percent of the phosphate mined becomes fertilizer. That's why there's such an overwhelming need to continue phosphate mining - and why Mosaic's Florida phosphate operations are so vital to our future. Chief among these is rock phosphate, or phosphorite. Estimates of the amount available range from 9 to 22 million tonnes of uranium. The World Distribution of Uranium Deposits database tabulates 14 million tonnes, though the Red Book tabulates only million .
The wet process involves treating the rock phosphate with acid-producing phosphoric acid – also called green or black acid – and gypsum, which is removed as a by-product. The impurities that give the acid its color haven’t been a problem in the production of dry fertilizers. Orthophosphoric acid.

Phosphogypsum is a by-product of the chemical reaction called the “wet process,” whereby sulfuric acid is reacted with phosphate rock to produce the phosphoric acid needed for fertilizer production.
PRODUCTION AND USE OF BY-PRODUCT GYPSUM IN THE CONSTRUCTION INDUSTRY Wojciech Roszczynialski, Marek Gawlicki and Wieslawa Nocud -Wczelik INTRODUCTION Two groups of gypsum by-products have been identified: chemical gypsum and desulphogypsum.
The data dealing with the other chemical gypsum utilization are not readily available. This results Cited by: 4. American Society for Testing and Materials, Annual Book of ASTM Standards, VolumeASTM, West Conshohocken, Pennsylvania, Taha, Ramzi and Roger Seals.
"Engineering Properties and Potential Uses of By-Product Phosphogypsum." Proceedings of Utilization of Waste Materials in Civil Engineering Construction. Malinowski et al. () made a study on the utilization of waste gypsum in fertilizer production and concluded that by-product gypsum can be used for the production of the granulated fertilizers.
Phosphogypsum is a waste by-product from the processing of phosphate rock in plants producing phosphoric acid and phosphate fertilizers, such as superphosphate.
The wet chemical phosphoric acid treatment process, or ‘wet process’, in which phosphate ore is digested with sulfuric acid, is widely used to produce phosphoric acid and calcium sulfate, mainly in dihydrate form (CaSO 4 · 2H 2 O). The optimum conditions of the treatment are 8 M sulfuric acid solution and 1/4 solid/liquid ratio for 30 min contact time at 80 °C.
Moreover, the optimum conditions of the ammonium sulfate preparation are 10 g of the suspended impure or purified phosphogypsum in 40 ml of 3% ammonium sulfate solution (as initiator), Cited by: In Florida, the phosphate rock is sent to processing plants in which it undergoes "wet process" to convert it into phosphoric acid.
In the process, sulfuric acid is added to the phosphate to create phosphoric acid — which is easily absorbed by plants. Phosphogypsum (or “gypsum”), a radioactive material, is a byproduct of this process.

Radiation and Phosphogypsum • Both natural gypsum and phosphogypsum contain radioactivity, but phosphogypsum contains more. • In the manufacture of phosphoric acid, the acid is filtered through cloth to remove solids. The radium is filtered out with the solids.
The solid portion is known as phosphogypsum. EVALUATION OF POTENTIAL COMMERCIAL PROCESSES FOR THE PRODUCTION OF SULFURIC ACID FROM PHOSPHOGYPSUM FINAL REPORT By ZELLARS-WILLIAMS, INC. O, Box Lakeland, Florida - Principal Investigator: A. Kouloheris Prepared for FLORIDA INSTITUTE OF PHOSPHATE RESEARCH The widespread availability of natural gypsum.
Status Quo of Phosphate Fertilizer Industry — Environment Gypsum, Land Clean production, environmentally friendly discharge Status Quo of Phosphate Fertilizer Industry — Environment Gypsum is a byproduct of wet process phosphoric acid (WPPA), and while producing a ton of WPPA (%P2O5), about 5 tons of gypsum (dry basis) will be generated.
America is blessed with abundant low-cost natural gypsum. There is also an abundance of flue gas desulfurization gypsum produced as a by-product of coal-fired power plants. As a result, the market for the phosphogypsum generated by the chemical processing of phosphate.
