overhead. This method of gypsum mining produces approximately 90,000 to 160,000 tons of ore a year. The largest gypsum quarry in the world, Gold Bond’s Milford, Nova Scotia operation, produces four and a half to five million tons of ore per year. The quarry process begins by first removing the earth over the deposit. Then gypsum ore is drilled
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 gypsum products.
Gypsum is used as a building material, making writing chalk, as a soil conditioner . and Process Industries Mining and Mineral Industries Gypsum Processing. Calcination Wikipedia The IUPAC defines calcination as "heating to high temperatures in air or oxygen".

Gypsum plaster is a white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added. Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water.
