  • Study on Preparation of High-Strength Gypsum by FGD Gypsum

    With the enlarging of industrial desulfurization the amount of FGD gypsum is increasing rapidly. The preparation of alpha-calcium sulfate hemihydrate (α-HH) is one of the biggest concerns for FGD gypsum reclamation. The influence of mixed chlorate solution of Mg-Ca-Na concentrations (5-30 wt ) and FGD gypsum concentrations (5-30 wt ) by hydrothermal salt solution method at atmospheric
