Gypsum Manufacturing Process Description12 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
Phosphogypsum refers to the calcium sulfate hydrate formed as a byproduct of the production of fertilizer from phosphate is mainly composed of gypsum (CaSO 4 #183;2H 2 O). 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.

Phosphogypsum, Gypsum, and Other Industrial Byproducts Korcak This chapter provides information about several industrial byproducts and agricultural uses for these byproducts. The focus is on relatively new industrial byproducts for which significant data have accumulated over the past 10 to 15 yr. Also included are some
Phosphogypsum is a waste byproduct 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 #183; 2H 2 O):
Abstract. Phosphogypsum is a byproduct created during the production of industrial wetprocess phosphoric acid. This study focused on recovering rare earth elements (REEs) from a Florida phosphogypsum sample and investigated the effects of removing detrimental impurities such as phosphorus pentoxide (P 2 O 5), uranium (U) and fluorine (F) during the leaching process.

FIELD: chemistry. SUBSTANCE: invention pertains to the technology of complex processing of phosphogypsum, obtained during sulphuric acid conversion of apatite concentrate to mineral fertilisers. Phosphogypsum is leached by a 2230% solution of sulphuric acid for a period of 2025 minutes, turning phosphorous and lanthanides into a leaching solution and a gypsum residue is obtained.
The calcium carbonate resulting from the aqueous process together with the other insolubles found in phosphogypsum was to be used as a feedstock to a ceramic tile manufacturing process. Laboratory tests were used to assess the feasibility of the aqueous process and the ceramic tile process.
