• Gypsum Mining in Cumbria - Visit Cumbria

    Gypsum Mining in Cumbria. Gypsum (hydrated calcium sulphate) has been quarried or mined at Kirkby Thore for over 200 years. The gypsum is ground to a powder and heated to evaporate water.

  • Mineral Planning Factsheet Gypsum

    When gypsum (CaSO4.2H2O) is ground to a powder and heated at 150° to 165°C, three-quarters of its combined water is removed producing hemi-hydrate plaster (CaSO4.1/2 H2O), commonly know as Plaster of Paris. When this powder is mixed with water the resulting paste sets hard as the water recom-bines to produce gypsum again. This process can be repeated almost indefinitely with important ...
