#0183;#32;An example of this material is the Phosphogypsum (PG), which results from the processing of phosphate ore into phosphoric acid for fertilizer production. In order to support regulation of the reuse of phosphogypsum as a raw material of the Brazilian civil
The challenges of producing sulphoaluminate cement with phosphogypsum. At present, there is a lot of researches on the application of phosphogypsum in the production of sulphoaluminate cement at home and abroad, which mainly focuses on the use of phosphogypsum as the cement retarder and the production of sulphuric acid integrated with sulphoaluminate cement.

Application of phosphogypsum in soil stabilization
Th e Application of Phosphogypsum in Agriculture USA. Th e production is constantly increasing, and it is expected to reach 200250 million tons in the next decade (IAEA, 2013). Given the large quantities that are produced, and having in mind
Phosphogypsum was utilized via dispersed application into a soil layer of 2045 cm with intrasoil milling of this layer. The phosphogypsum utilization doses were 0, 10, 20, and 40 t ha1.
Phosphogypsum is used as the granulating agent and carrier for urea to prepare phosphogypsumgranulated urea, then the fertilizer core is coated by paraffin, which contains Span80 5% to improve theadhesion between paraffin and the fertilizer core. The results show that: less than 35% of urea from bothparaffincoated phosphogypsum granulated urea is released in water during 28
Subsoil acidity is recognized as one of the most important yieldlimiting factors in strongly acid nonallophanic Andosols. Surface application of phosphogypsum (PG) has the potential to ameliorate subsoil acidity in these soil. According to humus content, two types of nonallophanic Andosols were selected as test soils. The Kitakami soil (Lightcolored Andosol) has low humus content and the

The radiological concerns associated with phosphogypsum utilization as a substitute for natural gypsum in agriculture have been placed in perspective by considering the consequences of a hypothetical case involving heavy long term applications of phosphogypsum. Such a schedule might consist of an initial gypsum application of 10 tons/acre followed by alternate year applications of 5
