Most gypsum mines are simply operations that dig up gypsum and crush it to size. Natural gypsum may be upgraded, usually by washing, to decrease the amount of clay in the rock. By-product, or synthetic, gypsum is viewed as environmentally-friendly because it incorporates sulphur removed during flue gas desulfurization (FGD) at coal-fired power plants and other industrial sites.

The 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 ore, from quarries and underground mines, is crushed and stockpiled near a plant. Asneeded, the stockpiled ore is further crushed and screened to about 50 millimeters (2 inches) in diameter. If the moisture content of the mined ore is greater than about 0.5 weight percent, the ore must be dried in a rotary dryer or a heated roller mill.

A foremost element of the mining process is breaking up the rock. This breakup is accomplished by detonating volatiles set in blast holes. The rock face to be gusted is typically 40-feet in width by 20- to 25-feet high. A premeditated pattern of 40 to 50 horizontal holes are drilled for the dimensions of 2 inches wide by 12- to 14-feet deep.

The use of restoration techniques such as hydroseeding or ECBs have largely proven to be effective (Brofas & Varelides, 2000), also for gypsum habitats (2012, Ballesteros et al., 2017). However, for more level areas this adds unnecessary costs (between 4400 and 15,900 €/ha), that would be only justified for small patches to treat stabilization or erosion problems.
