The mineral composition of FGD gypsum and mined gypsum is predominantly CaSO₄•2H₂O. Occasionally, FGD gypsum contains minor amounts of quartz (SiO₂). Mined gypsum contains both quartz and dolomite
Gypsum is a mineral (CaSO 4 ·2H 2 O) that occurs in nature as both a mineral and, when in massive form, a rock. Massive deposits are present as sedimentary beds of varying thickness in the subsurface within the Trinity Group in southwest Arkansas.
Plaster of Paris is dehydrated gypsum. Gypsum is a naturally forming nonmetallic mineral, found as a rock or sand composed of % calcium sulphate and % water by weight. Its chemical formula is CaSO 4 • 2H 2 O. Gypsum is found naturally in most parts of the world. In addition to mined gypsum there is ''Byproduct'' gypsum.

America is blessed with abundant lowcost natural gypsum. There is also an abundance of flue gas desulfurization gypsum produced as a byproduct of coalfired power plants. As a result, the market for the phosphogypsum generated by the chemical processing of phosphate rock has traditionally been limited. It has traditionally been piled on land.
Mining of gypsum is simple and easy, as the mineral occurs in large thick beds near the Earth''s surface. However, largescale mining of gypsum involves considerable damage to the environment. Gypsum can also be recycled, but not much importance has been given to recycle this mineral .
Gypsum has the same chemical composition as the mineral Anhydrite, but contains water in its structure, which Anhydrite lacks. Many Anhydrite specimens absorb water, transforming into the more common Gypsum. Some Gypsum specimens show evidence of this, containing growths of crumpling layers that testify to their expansion from the addition of ...
Gypsum is a common mineral. It is found in layers that were formed under salt water millions of years ago. When water evaporated, it left the mineral behind. Gypsum is mined from sedimentary rock formations around the world. It takes the form of crystals which can at times be found projecting from rock – leading to its old English name of the ...

Gypsum is a very soft mineral that is easily identified by its hardness, cleavage, and solubility in water. Typically clear to white, gypsum may be colored reddish to brown or yellow if impurities are present. Most gypsum occurs in its massive form, as layers of rock that often intercalate layers of shale, limestone, or dolostone.
