    Abstract. 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 138ton exceeds the rough estimated cost of ammonium sulfate from the proposed process
