Gypsum Mineral Uses and Properties

What is Gypsum? 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.
