Flue gases: Gypsum dewatering in desulphurisation
Gypsum dewatering process stage. High quality limestone that is finely ground (typically 90% is smaller than 45μm), excellent flue gas particle removal upstream of the scrubber and a low calcium sulphite content are pre-requisites for producing high quality gypsum. In order to qualify as a valuable gypsum product not only is the water content ...
Gypsum Mining | Processing Equipment | Flow Chart
Canada, Mexico and Spain are other significant producers of raw 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.
