Abstract
Two new processes are introduced for SA and sulfate production from phosphogypsum. In view of the high temperature decomposition outside kiln, the optimum condition is studied in the laboratory，with the discussion on the double industrialization possibilities for the by-product cement or calcium carbide respectively. For the reaction coupling process，the reaction coupling system is simply introduced, which is with the partly-penetrating membrane as the separation unit and driven by electronic field, the current efficiency of experiment can be over 90%.
