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.
The gypsum is typically extracted from the ground using one of two main methods: underground mining or open-pit mining. Underground mining involves creating shafts and tunnels to access the gypsum deposits.

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. Moreover, gypsum is used worldwide in concrete for highways, bridges, buildings, and many other structures that are part of our everyday life.
Deep below the rugged surface of Indiana's Martin County people work in two underground mines to extract and process an unusual mineral resource - gypsum. Gypsum (CaSO4*2H2O) is a soft, water soluble mineral that is processed to make critical building materials especially wallboard. Gypsum is mostly massive (Fig. 1A) but also forms silky satin spar (Fig. 1B).

Gypsum Mining. Gypsum is commonly found in sedimentary rock formations. It's extracted from open-pit mines or underground mines using large drills and blasting with explosives. The way gypsum is mined depends on the hardness of the gypsum and the size and depth of the deposit. If the gypsum is located close to the surface and the deposit is ...
Most crude gypsum produced in the United States originates from open-pit mines west of the Mississippi River. Processing is typically limited to drying, crushing, screening and calcining.
The Glitter Mountain mine (aka Sparkle Mountain or the Old Gypsum Mine) contains deposits of a transparent crystalline form of gypsum called selenite. There's an active mining claim at the pit, but luckily, they allow visitors. What You Need to Know Before Visiting Glitter Mountain
