The physical nature of these materials varies from a wet, thixotropic sludge to a dry, powdered material, depending on the process. FGD units remove SO 2 from flue gas but, in doing so, generate large quantities of synthetic gypsum (FGD material), which is a mixture of gypsum (CaSO 4 C 2 H 2 O), calcium sulfite (CaSO 3), fly ash, and unreacted ...
Jul 16, 2020· Gypsum outcrops are widespread throughout the world but typically occur in arid and semiarid ecosystems. The soils of these outcrops are restrictive and impose harsh abiotic conditions on the plants growing in them. Despite this making them an ideal system to analyse community assembly under harsh conditions, questions remain about this process.
