Gypsum - Wikipedia
Gypsum is moderately water-soluble (~2.0–2.5 g/L at 25 °C) and, in contrast to most other salts, it exhibits retrograde solubility, becoming less soluble at higher temperatures. When gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate (bassanite, often simply called "plaster") and, if heated further, to anhydrous calcium sulfate (anhydrite). As with anhydrite, the

GYPSUM IN SOUTH AFRICA - Department of Mineral Resources
The processing of gypsum depends on the end use. There is little or no beneficiation. Nearly all-commercial gypsum is calcined. Generally gypsum is ground, calcined at 250oC for 2 hours and then at 300-350oC, when it loses 75% of its water of crystallization and forms the hemihydrate (CaSO 4. ½ H 2O), known as plaster of Paris, stucco or plaster.
