Gypsum - Hosokawa Micron Powder Systems

Gypsum is a mineral composed of calcium sulfate dihydrate (CaSO4-2xH20), which is formed when a lake or sea has evaporated. The gypsum is then mined from the evaporated beds. Another way gypsum is formed is during the flue gas desulfurization process in power stations. Gypsum is used in construction, especially in sheet-rock and wall finishing. …

Gypsum Mineral | Uses and Properties

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.
