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.
Gypsum Manufacturing Process Description12 Gypsum is calcium sulfate dihydrate (CaSO4 2H2O), a white or gray naturally occurring mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or
Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.
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.
