phosphoric acid plant and synthetic gypsum plant
Phosphogypsum
Phosphogypsum (PG) is the calcium sulfate hydrate formed as a byproduct of the production of fertilizer from phosphate rock It is mainly composed of gypsum (CaSO4·2H2O) Although gypsum is a widely used material in the construction industry, phosphogypsum is usually not used, but is stored indefinitely because of its weak radioactivity caused by the presence of naturally occurring uranium (At the production of phosphoric acid the residue gypsum is generated, called phosphoric acid gypsum, or also phosphoric gypsum for brevity's sake Processing and Application of Phosphoric Gypsum

The objective of this project is to design a plant to produce 200,000 TONE/YEAR of Phosphoric acid based on the most effective method, considering factors and presenting all possible methodsPhosphogypsum formed from the production of phosphoric acid represents by far the biggest accumulation of gypsumrich wastes in the world and commonly contains Uptake and speciation of uranium in synthetic gypsum
Circular Process for Phosphoric Acid Plant Wastewater
Phosphoric acid production generates large volumes of industrial wastewater that cannot be treated efficiently by existing processes because of its low pH The phosphoric acid and sulfuric acid plants ceased operations in 2018 and as such, the Gypsum Stacks also ceased receiving phosphogypsum generated from PCS Nitrogen Fertilizer, LP Settlement Information Sheet
