What is gypsum manufacturing?
FGD Gypsum Production Process – Gypsum Association
FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum.

Gypsum Processing - FEECO International Inc.
Gypsum can be a difficult material to process, from its variability, to its tendency to harden into a cement-like form, and its abrasive nature. For this reason, choosing processing solutions that are heavy-duty and designed around the unique characteristics of the gypsum sample to be processed will offer the best results.
Making Gypsum Board – Gypsum Association
End tapes are applied that identify manufacturer, facility, production line, date and time of manufacture as well as country of origin are applied per GA-1000 Identification of Gypsum Board. Ready for installation, the panels are stored and distributed on risers of uniform height to ensure the gypsum panel products are supported evenly.

Molding process Calcined “gypsum” is mixed with water to make a slurry (muddy state). Then, the slurry is poured into a line (belt) where board liners are flowing down, thus sandwiched with board liners.
Gypsum Products - CECO Environmental
In Gypsum Product Manufacturing, the chemical composition of gypsum is calcium sulfate dihydrate (CaSO4·2H2O). There are two types: natural gypsum and Flue-Gas Desulfurization (FGD) gypsum. FGD gypsum is a by-product of desulfurization of flue gas from the stacks of fossil-fueled power plants.

Gypsum block - Wikipedia
Manufacture. A gypsum block is made of gypsum plaster and water. The manufacturing process is automated at production plants where raw gypsum (CaSO 4 ·2H 2 O) is ground and dried, then heated to remove three-quarters of the bound water and thus transformed into calcium sulfate hemihydrate (CaSO 4 ·½H 2 O), also known as gypsum plaster, stucco, calcined gypsum or plaster of Paris.
