Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.

Gypsum is an excellent source of sulfur for plant nutrition and for improving crop yield. It also improves acid soils and treats aluminum toxicity. One of gypsum's main advantages is its ability to reduce aluminum toxicity, which often accompanies soil acidity, particularly in subsoil. Besides this, gypsum is used to improve soil structure.

Production processes Gypsum processing plants vary widely in scale and level of technology. They range from plants producing one or two tonnes per day using low-cost manual technologies, to plants of a thousand tonnes per day that are highly mechanized and capable of producing different types and grades of gypsum plaster or plaster boards.
