Plaster of Paris is de-hydrated gypsum. Gypsum is a naturally forming non-metallic mineral, found as a rock or sand composed of 70.1% calcium sulphate and 20.9% water by weight. Its chemical formula is CaSO 4 • 2H 2 O. Gypsum is found naturally in most parts of the world. In addition to mined gypsum there is ‘Byproduct’ gypsum.
Gypsum is commonly associated with rock salt and sulfur deposits. It is processed and used as prefabricated wallboard or as industrial or building plaster, used in cement manufacture, agriculture and other uses. Gypsum Mining. IMAR 7 th Edition. Most of the world’s gypsum is produced by surface-mining operations.
Gypsum mining has a long history in Kansas, dating to the mid- to late-1800s. The first gypsum deposits worked in the state were near Blue Rapids in Marshall County. Both the Marshall County and Barber County plants have underground mines but the majority of gypsum in Barber County is produced from an open pit.
The gypsum slurry is then extruded between paper backing, and, after setting up, sheets are cut to specific sizes. Drying in large gas-fired ovens cures the wallboard. The final product is shipped by either truck or rail from the plant facility. Mining Gypsum was first mined in Arkansas in 1922, with continuous production starting in 1936.
