The most common method is autoclaving with subsequent drying and grinding. The last two processes can be conducted with the same equipment Fig. 25.8. Hemihydrate drying at atmospheric pressure is substituted for evaporation at a pressure 0.1 MPa.Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum CaSO 4. 2H 2 O is very similar to Anhydrite CaSO 4. The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.Mar 15, 2020 2.3.4. Synthesis of gypsum. After the recovery of Fe-species, the treated water was rich in sulphate, which was recovered by adding 5 g of lime per L of treated water, thus leading to the formation of calcium sulphate gypsum Liu et al., 2016.The product slurry was recovered as described in Section 2.2.1 and then dried at 105 C for 24 h.
