A Comparative Study on the Basic Properties of FGD Gypsums

Compared with natural gypsum, the basic properties of FGD gypsum are studied based on the test results and then the influence of FGD gypsum’s chemical constituents, impurities and particle size distribution on its products is analyzed. The results indicate the impurities play an important role on the FGD gypsum behavior. Finally, the differences between FGD gypsum and natural gypsum are summarized.
