  • A Comparison of Properties of FGD and Natural Gypsum

    Formation of FGD Gypsum. On formation of a precipitate from solution, dissolved constituents must partition between the solid and liquid phases. There is evidence that mercury tends to partition to the solid phase. There is also evidence that other heavy metals tend to partition to the liquid phase.
