Mineral carbonation of flue gas desulfurization .

1/11/2012· Waste gypsum is an industrial waste that falls in two categories: flue gas desulfurization (FGD) gypsum and phosphogypsum. FGD gypsum is mostly generated in the process of SO x elimination from power plant flue gas, while phosphogypsum is generated when phosphate fertilizer is produced by acid treatment of phosphate rock.
