The production of ammonium sulfate fert ilizer from phosphogypsum is studied. The phosphogypsum is considered by prod uct from extraction process of sulphoric acid. The mereseberg process is used a waste of phosphogypsum with ammonium carbonate to produce ammonium sulfate as a main product and calcium carbonate as a byproduct. …
