Gypsum is a naturally occurring mineral that is made up of calcium sulfate and water (CaSO 4 +2H 2 O) that is sometimes called hydrous calcium sulfate. It is the mineral calcium sulfate with two water molecules attached. By weight it is 79% calcium sulfate and 21% water. Gypsum has 23% calcium and 18% sulfur and its solubility is

gypsum was 18.0 million tons. Synthetic gypsum is mainly produced as a byproduct in flue gas desulfurization (FGD) systems. Calcined gypsum is produced domestically from crude gypsum by heating selenite. In the United States, gypsum is primarily used to manufacture wallboard and plaster for homes, offices, and commercial buildings.

Gypsum mining is the extraction of the mineral gypsum, a soft sulfate mineral composed of calcium sulfate dihydrate, from the Earth's crust. Gypsum is widely used in various industries, including construction, agriculture, and manufacturing. It is primarily used in the production of plaster, wallboard, cement, and fertilizers.
