Production of plaster from natural gypsum High-quality gypsum rock is extracted at quarries or mines. Large rocks are crushed into small pieces in a grinding mill. At some plants, the crushed rock undergoes a surface drying process before being grinded. The mill reduces small rocks to a very fine, chalk-like powder called land plaster.
