Gypsum/Anhydrite are produced from open-cast mines or underground mines using pillar and stall mining methods that give extraction rates of up to 75%. . product of a wet purification procedure with natural lime, that essentially forms according to the same laws as natural Gypsum–but in a speeded-up process taking only.

What is Gypsum? - Gypsum Association

Gypsum rock is mined or quarried, crushed and ground into a fine powder. In a process called calcining, the powder is heating to approximately 350 degrees F, driving off three fourths of the chemically combined water. The calcined gypsum, or hemihydrate, becomes the base for gypsum plaster, gypsum board and other.
