The fine powder of gypsum plaster could be used as building materials in the manufacture of new products including gypsum instead of natural gypsum cement retarder production, refining building gypsum powder, production of plaster board, gypsum block and the like. 2. phosphogypsum rendered acidic, is very rich in sulfur, calcium, magnesium and other trace elements, in addition of …
Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at ℃.

A process for reducing radioactive contamination of phosphogypsum. Phosphogypsum containing radioactive material is calcined to form hemihydrate crystals carrying the radioactive contaminants, and a portion of the crystals is converted to substantially radiation-free gypsum crystals which are readily separated from the hemihydrate crystal relics containing substantially all of the radioactive ...

11.16 Gypsum Manufacturing 11.16.1 Process Description1-2 Gypsum is calcium sulfate dihydrate (CaSO4 2H2O), a white or gray naturally occurring mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or
synthetic gypsum is produced by the neutralisation of sulphuric acid and lime. Countries with fertilizer industry can obtain gypsum as a by-product from the phosphoric acid manufacture. Gypsum plastm are made by calcining the raw gypsum so that dehydration to plaster of Paris or to anhydrous sulphate occurs. The first type is formed by partial ...
Gypsum is especially beneficial to clay soils and is also used to treat sodic soils. As a source of gypsum, phosphogypsum can and does substitute natural gypsum as a soil amendment in many countries, including Australia, Brazil, and Spain, to name a few. Studies have even found that the application of phosphogypsum can increase crop yields in ...
The results of this study indicate that phosphogypsum from each of the sources investigated has potential as a substitute for mined gypsum in gypsum products manufacture. Pilot-scale testing is recommended to confirm that the product would be satisfactory for the manufacture of plaster products on a commercial basis.
The phosphogypsum (PG) is a byproduct of the phosphate fertilizers manufacture. The world production estimated to 200 million tons per year induces environmental threats and storage problems, which requires strict policies to limit pollution and encourage its valorization.
It is found that the quality of the obtained phosphogypsum plaster comply with existing standards, and the firing time is reduced by several orders of magnitude compared to currently used machines. The resulting binder may be used to produce a wide range of gypsum building materials and products.
