Costs for constructing and operating a conceptual plant based on a proposed process that converts flue gas desulfurization (FGD)gypsum to ammonium sulfate fertilizer has been calculated and used to estimate a market price for the product. The average market price of granular ammonium sulfate (138/ton) exceeds the rough estimated cost of ammonium sulfate from the proposed process (111/
