Gypsum is a common mineral found in many places around the world The scientific name for raw gypsum is anhydrous calcium sulphate Gypsum contains a large amount of water in crystalline form The process of making gypsum products involves removal of the moisture content from the raw ore and reintroducing the moisture in the fabrication of gypsum wallboard products Plants for converting gypsum

Gypsum Wikipedia

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall A massive finegrained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including Ancient Egypt,

Phosphogypsum Wikipedia

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
