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.

Manufacturing Process - Gypsum

28/02/2016  Gypsum, often begins as calcium sulfate dissolved in an isolated body of salt water. As the water evaporates, the calcium sulfate becomes so concentrated that it can no longer remain in solution and crystallizes out (precipitates) as gypsum. Many large beds of gypsum have been formed in this way.

of the manufacturing process. The stucco is blended with water and other ingredients (depending on the type of wallboard being made) to make a “slurry,” or paste. This stucco slurry will then be spread onto paper to form wallboard. The “Bread” That Makes the Wall-board Gypsum wallboard is frequently described as a “sandwich,” with gyp-sum being the “meat” and paper being the ...
