Gypsum used for plaster manufacture usually contains at least 90% CaSO 4 2H 2 O, a maximum of 0.02% NaCl (salt), and approximately 2% acid insolubles. Another major use of gypsum is in the cement industry, where it is added at the rate of 2–5% to cement clinker prior to final grinding to retard the setting rate of concrete.

The mining technology used to exploit gypsum is the same as that used in other mining industries. To produce plaster, rock gypsum or alabaster scrap is transported to plaster mills where it is crushed and ground to powder prior to being heated in a kiln to remove most of its water content.
