The Technology

Phosphogypsum is a product of manufacturing of phosphoric acid from phosphate rock. It contains radioactive impurities and chemical impurities which deteriorate the gypsum quality. Huge quantities of phosphogypsum is piling next to quarries. Some process exists to clean the phosphogypsum to be usable by the construction industry, but they all can’t remove the radioactive impurities. The proposed method produces clean gypsum that can be used as starting material for many applications in the construction industry

Advantages

  • Produces clean gypsum
  • Eliminates the need to pile phosphogypsum

Applications and Opportunities

  • Construction materials
  • Materials for roads
