Abstract
This study is carried out for the purpose of investigating the property of phosphogypsum, and suggesting the proper recycling system for it. The chemical composition, mineralogical composition, particle size distribution and shape of phosphogypsum were investigated. The size distribution and constitution of impurities, distribution of heavy metals are also investigated. In conclusion, the grade and yield of recoverable phosphogypsum were discussed.
Keywords
