Abstract
This paper describes research into the conversion of phosphogypsum to sulfur, focusing on converting calcium sulfide to ammonium bisulfide by reaction of an aqueous slurry with ammonia and carbon dioxide. Calcium carbonate is removed by filtration, and the ammonium bisulfide is oxidized to sulfur using air in the presence of a carbon catalyst. Also included is a discussion of the reaction parameters and their effect upon sulfur yield.
