stripping in open pits (see photo below). After mining, the gypsum is processed into a variety of products, the most common of which are wallboard and plaster-of-Paris. To produce wallboard, the gypsum is "calcined," an industrial term for the process that includes the grinding of gypsum to a fine powder which is then heated for 2 to 3 hours.
Most gypsum in the United States is used to make wallboard for homes, offices, and commercial buildings; a typical new American home contains more than 7 metric tons of gypsum alone.
