About Gypsum

• It is a sedimentary rock primarily composed of calcium sulfate dihydrate (CaSO4 · 2H2O) and anhydrite (CaSO4).
• Gypsum is found in both crystal and rock forms. 
• Occurrence: It commonly occurs in extensive beds alongside evaporite minerals like anhydrite and halite, especially in Permian and Triassic sedimentary formations.
• It is often found in saline lakes and salt pans and constitutes a significant part of cap rock on salt domes,
• It generally results from the evaporation of saline water and is one of the more common minerals in sedimentary conditions.
• Gypsum that occurs in nature is called mineral gypsum.
• In India, marine gypsum is recovered from salt pans during production of common salt in coastal regions, particularly in Gujarat and Tamil Nadu.

Applications of Gypsum

• Agricultural use: It works as an agent to remove Saline/Alkaline ingredients in the soil. It acts more or less like manure.
• Industrial use: It is used in manufacturing lime and in the cement industry and also used in manufacturing Plaster of Paris.
