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. Heating to approximately 160C drives off a limited amount of water and Plaster of Paris is produced.

The two coal byproducts that can be reutilized are fly ash and gypsum
Gypsum is another coal byproduct that can be reused and used in cement for roads, bridges, buildings, and other structures worldwide. Recycling and repurposing gypsum minimizes the requirement for raw materials and has the potential to lower the cost of new drywall products (LINA, 2021).

Gypsum Board production flow
Calcined "gypsum" is mixed with water to make a slurry (muddy state). Then, the slurry is poured into a line (belt) where board liners are flowing down, thus sandwiched with board liners. Drying process Boards are sent to a drying machine (dryer) to remove excess water content. Finishing process Boards are cut into products with appropriate size.
