Unoxidized Lime/Limestone FGD products are thixotropic sludges (consistency of toothpaste—may liquefy when shaken) Difficult to dewater. Require some sort of processing or admixture such as fly ash or lime to achieve moisture levels that can be handled. Cannot be easily stored, transported or spread with conventional agricultural equipment.
Insoluble gypsum is separated from the reaction solution by filtration. Operating conditions are generally selected so that the calcium sulfate will be precipitated in either the dihydrate or the hemihydrate form, thus producing 26-32% P2O5 at 70-80°C for dihydrate precipitation and 40-52% P2O5 at 90-110°C for hemihydrate precipitation.

ASTM standards govern the manufacture of gypsum board and set strict criteria for strength, water resistance, and other characteristics. To produce gypsum board, crushed natural gypsum or synthetic gypsum is heated or calcined to dehydrate the feedstock. Next the calcined gypsum is mixed with water and additives to form a slurry which is fed.
