Abstract：The production technology of sulfuric acid by phosphogypsum decomposition with sulfur is putforward to solve the existing problems of sulfuric acid production process by phosphogypsum. The researchcontents, general technical route, and typical test results are introduced. The advantages and promotioncharacteristics of sulfuric acid production technology by phosphogypsum decomposition with sulfur are putforward. The new way of production sulfur acid by phosphorusypsum decomposition with sulfur, can reduce thedecomposition temperature of phosphogypsum,improve the concentration of sulfur dioxide in flue gas,extendthe utilization scope of calcium in phosphogypsum. The technology is proved to be feasibility after small test,pilot test and ten thousands ton device test.
