Gypsum, also known as "anhydrite" in the World Bank's WITS format, is a valuable mineral commodity that plays a significant role in various industries. It forms naturally through the evaporation of bodies of water or as a result of decomposition.
Gypsum has diverse uses including construction, where it serves as a key component in products such as drywall and plaster, agricultural applications as a soil conditioner, and industrial production of fertilizers and diapers. Anhydrite, a sulfate mineral, is often used as a substitute for gypsum due to its higher heat resistance and slower setting characteristics.
Gypsum and anhydrite are traded in various forms including raw mineral, crushed stone, and processed powder, sourced from open-pit or underground mines. The production process involves crushing, grinding, and heating to produce calcined gypsum or crushed anhydrite, which can be further processed into different products.
