11.16 Gypsum Manufacturing 11.16.1 Process Description1-2 Gypsum is calcium sulfate dihydrate (CaSO4 2H2O), a white or gray naturally occurring mineral. Raw gypsum ore Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO42H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, drywall and blackboard or sidewalk chalk. Gypsum also crystallizes as translucent crystals of selenite. It forms as an evaporite mineral and as a hydration product of anhydrite. The Mohs scale of mineral hardnessGypsum

Gypsum is a mineral consisting of water-containing calcium sulphate (CaSO 4. 2 H 2 O). When calcined (roasted) at temperatures of 120-250°C, gypsum releases 75% of its water. The resulting plaster of Paris, when mixed with water, can be molded, shaped or spread, then dried or set to form hard plaster. Gypsum was used by The gypsum comes at the forefront of these products in terms of availability of raw material and low manufacturing costs, where Sudan's stockpile of gypsum is estimated at 300 million tons.
