Plaster of Paris is de-hydrated gypsum. Gypsum is a naturally forming non-metallic mineral, found as a rock or sand composed of 70.1% calcium sulphate and 20.9% 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.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. 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 fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many .

Gypsum is a common mineral obtained from surface and underground deposits. It can be a valuable source of both calcium (Ca) and sulfur (S) for plants and can benefit certain soil properties under specific conditions. Production. Gypsum is found in both crystal and rock forms.
There are 27 gypsum mountains in Florida, with most concentrated in the Bone Valley region of southern Polk, eastern Hillsborough and Hardee counties. Ten are still active and continue to receive the byproducts of phosphate mining and processing. Estimates peg the amount of gypsum in the stacks at 700 million tons.
The term "coal combustion byproducts" (CCB) includes fly ash, bottom ash, boiler slag, and FGD (flue-gas desulfurization) material known as synthetic gypsum.An American Society for Testing and Materials (ASTM) subcommittee under Committee E-50 on Environmental Assessment addressed the question of standards and definitions of coal and CCB terms.
In 1902, 30 independent gypsum rock and plaster manufacturing companies merged to consolidate their resources and form the United States Gypsum Company. The new company combined the operations of 37 mining and calcining plants producing agricultural and construction plaster.
Introduction to FGD Gypsum. FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from combustion gases using "scrubbers."
