British Gypsum: Brightling gypsum mine
07/08/2012The British Gypsum Brightling mine, near the Robertsbridge wallboard plant in East Sussex, has been in operation since the early 1960s. In the 1970s and 1980s it supplied up to 0.8Mt/yr of gypsum to the Robertsbridge wallboard plant, first via an aerial ropeway system and then a 4.7km-long conveyor, which was installed in 1989.

Gypsum Overview
When gypsum mining started in Nova Scotia in the late 1700s, it was done by farmers who extracted blocks of it from their farms, hauled it by horse and cart to shipping points near Windsor and sold it to local traders. The gypsum was then exported to the east coast of the United States for use as fertilizer. Gypsum fixes alkaline (high pH) soil.

Gypsum Plasterboard and the environment
'Stucco' is produced by removing around 75% of the water from the gypsum through heating using natural gas to a temperature of over 150'C. This process of 'calcination' changes calcium sulphate from its dihydrate state (gypsum) to its hemihydrate state. The hemihydrate calcium sulphate (CaSO 4 .H 2 O) is now ready to form plasterboard.

Gypsum is the neutral salt of a strong acid and strong base and does not increase or decrease acidity. Dissolving gypsum in water or soil results in the following reaction: CaSO 4 2H 2 O = Ca 2 + + SO 4 2- + 2H 2 O. It adds calcium ions (Ca 2 +) and sulfate ions (SO 4 2-), but does not add or take away hydrogen ions (H+).
