Gypsum
In all, more than 90 countries produce gypsum. In most open pit gypsum operations, benches are drilled and blasted using ammonium nitrate as the explosive. Because gypsum is so soft, most drills can drill through it at a rate of roughly 23 ft per minute. Sometimes the drill holes become wet, which can cause problems with the ammonium nitrate.

FGD Gypsum Production Process
To make FGD gypsum, the sludge is oxidized by forcing clean, compressed air through it. In the oxidation vessel, calcium sulfite sludge is converted to calcium sulfate (CaSO 4), which almost immediately combines with some of the water in the slurry to form calcium sulfate dihydrate (CaSO 4 ·2H 2 O). The resulting slurry is often referred to as ...
