Calcium Sulphate Dihydrate (Gypsum) is commonly hydrated by groundwater. The UK is largely selfsufficient in gypsum. The material can be found in seams in the Pennines and the Midlands, but the biggest source of extraction is in East Sus where mining extracts some 100,000 tonnes of gypsum a year from 100 m below the High Weald.

Fluegas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2 ) from exhaust flue gases of fossilfuel power plants, and from the emissions of other sulfur oxide emitting processes ( trash incineration )
flows through the Middle Eocene (Lutetian) gypsum towards the River Seine. Gypsum karstification and collapses tend to occur in areas where high groundwater gradients and the presence of gypsum of the Brackish Marl and Limestone coincide, but the subsidence hazard is reduced in areas of thick overburden (Thierry et al., 2009).
Gypsum, but is comparatively limited in its technical applications. The content of Gypsum in sedimentary rock varies from 75% to 95%, the rest being clay and chalk. B. Extracting Natural Gypsum Gypsum/Anhydrite are produced from opencast mines, or underground mines using pillar and stall mining methods, that give extraction rates of up to 75%....

The company already has permission to quarry gypsum at Bantycock. The latest application gives the plans for the phasing of gypsum extraction as well as its proposal for how the land will be restored once the work is complete.
The beauty of Gypsum is its sustainability throughout the life cycle of the product: from extraction to manufacturing, use in construction, renaturation and recycling into the same product.
opencast extraction is the only feasible method of working. The gypsum seams dip southeastwards beneath younger cover rocks where opencast extraction remains feasible, providing the overburden to mineral ratio is within the prevailing technical and economic limits. In contrast, the Tutbury gypsum normally comprises a single seam which is
