- ... BACKGROUND: In this study, a flue gas desulfurization (FGD) gypsum was calcined as phosphate sorbent materials for the remediation of phosphate wastewater. RESULTS: In addition to the main crystalline phase of gypsum, FGD gypsum contains a small quantity of quartz, dolomite, calcite and magnesite. Moreover, FGD gypsum has a prismatic structure with a dense and smooth surface, whereas a pore struct ...
