  • Gypsum Minerals Education Coalition

    CharacteristicsProductionUsesGypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers. It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum. Gypsum is commonly as
  • Gypsum - minerals.statedevelopment.sa.gov.au

    Gypsum as mined is too high in salt content for plaster manufacture, so it is stockpiled on site for several years to allow leaching by rainwater. When the salt content has been sufficiently reduced, the gypsum is railed 64 km to a 160 000 t stockpile at Thevenard for loading on ships by conveyor. Lakes near Streaky Bay . The largest known undeveloped deposit in South Australia is 26 km south ...

  • 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. Gypsum is the most common sulfate mineral.
