W is the mass of gypsum (g). RESULTS AND DISCUSSION Effect of gypsum mass The effect of gypsum mass on the reduction of phenol concentration was studied by varying the mass at the initial phenol concentration of mol/L. As seen in Fig. 1 and Table 1, as the mass of gypsum was increased from to 3 g, the percentage of phenol removed on the
wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure In this process gypsum is crushed, dried, ground, and calcined.
(Fig. 2). In this process, the gypsum is dried and ground to the required fineness of the plaster in the mill. Thanks to the relatively high temperature level in the gypsum calcining mill, the gypsum is simultaneously calcined. When gypsum is calcined in an atmosphere saturated with water vapour at an overpressure of

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 ...
