Purity Determination in Gypsum Application Note Gypsum
Purity of gypsum is important to know, e.g. plasterboard typically requires a minimum of 70% gypsum. Synthetic/FGD Gypsum An alternative source of gypsum is synthetic gypsum derived as a side product from the flue gas desulfuriza tion (FGD) process – the socalled FGDgypsum. FGD plants are typically used at fossil
