A number of power plants convert the CaSO 3 to calcium sulfate (CaSO 4) by forced oxidation and take appropriate measures to reduce other impurities in the synthetic material and, thus, produce synthetic gypsum that meets or exceeds the specifications for wallboard manufacture. Wallboard plants that have been constructed adjacent to such ...
Introduction to FGD Gypsum. FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from combustion gases using "scrubbers."
Gypsum/Anhydrite are produced from open-cast mines, or underground mines using pillar and stall mining methods, that give extraction rates of up to 75%. Gypsum is normally only screened to remove 'fines' (mainly mudstones), then crushed and finely ground. Gypsum/Anhydrite for cement manufacture is supplied in crushed form for further fine
Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker—the main ingredient of cement—that is finely ground with gypsum and other chemical additives to produce cement.
