Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
Phosphogypsum Stacks. 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.
wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure In this process gypsum is crushed, dried, ground, and calcined.
