| Abstract: | In ammonium phosphate production a large quantity of waste phosphogypsum is to be discharged, which not only occupies a lot of land for piling up but also pollutes the environment.The author describes the production of ammonium potassium sulfate from waste phosphogypsum in a pilot plant of 3 000 t/a, including the double decomposition reaction of phosphogypsum with ammonium carbonate to give ammonium sulfate and that of ammonium sulfate with potassium chloride to produce ammonium potassium sulfate. |
