The Role of Drying in Gypsum Mineral Processing. After gypsum ore is extracted from mines or quarries, it is crushed and stockpiled as needed. If the gypsum ore’s moisture content is greater than 0.5 weight percent, then the material requires drying. A gypsum dryer is commonly used to reduce the moisture content of the ore to the necessary level.

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

Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation – and frequently occurring with Gypsum – is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly. Anhydrite
