• Five stages of gypsum production process | Stone Crusher

    · Gypsum production process Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant Asneeded, the stockpiled ore is further crushed and screened to about 50 millimeters (2 inches) in diameter If the moisture content of the mined ore is greater than about 05 weight percent, the ore must be dried in a rotary dryer or a heated roller mill Ore dried in a rotary

  • Mechanism of water extraction from gypsum rock by

    · Microorganisms attach and form biofilms on the {011} planes of gypsum crystals; gypsum dissolves, and water extraction occurs Based on the crystal structure of gypsum, the water of crystallization layer is exposed to the {011} planes, but not to the {010} planes As the single crystalline gypsum dissolves and loses water of crystallization, it transforms via precipitation of nanocrystalline
