11.16 Gypsum Manufacturing - US EPA
11.16 Gypsum Manufacturing 11.16.1 Process Description1-2 Gypsum is calcium sulfate dihydrate (CaSO4 2H2O), a white or gray naturally occurring mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum
Gypsum processing and use - Humanitarian Library
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. There are five basic stages in

The process technology of the plant includes from extraction of gypsum to crushing, sifting, calcinations, grinding, mixing, testing and eventually packaging. The machinery and equipment required for mining will include wagons, drills with rod bits, compressors, loaders, bulldozers, rippers and trucks, etc.
