Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120180℃. Many systems additionally include options for grinding capacity

It is mainly composed of gypsum (CaSO 4 ·2H 2 O). Although gypsum is a widely used material in the construction industry, phosphogypsum is usually not used, but is stored indefinitely because of its weak radioactivity. The longrange storage is controversial. Somewhere between 100,000,000 and 280,000,000 tons are estimated to be produced annually as a consequence of the processing of

SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g).

Gypsum is the neutral salt of a strong acid and strong base and does not increase or decrease acidity. Dissolving gypsum in water or soil results in the following reaction: CaSO 4 ·2H 2 O = Ca 2 + + SO 4 2 + 2H 2 O. It adds calcium ions (Ca 2 +) and sulfate ions (SO 4 2), but does not add or take away hydrogen ions (H+). Therefore, it does
