Abstract: The present work aims to study the effect of two ways of phosphogypsum treatment using the organic and mineral solution to remove organic matter and P2O5 impregnated in phosphogypsum. The presence of these impurities in PG affect its application such as the non-dryness of the cement, i. e. , the delay of setting, and the problem of tiles breakage. Actually, we carried out a solid-liquid extraction test at the laboratory scale, using an organic solution and comparing it at some time to leaching by the mineral solution method. The results obtained show that solid-liquid extraction by organic solvent improves the extraction efficiency of P2O5 and eliminate the organic matter without changing the crystallography structure of PG with a yield of 100 %, and 47 % for OM and P2O5 respectively.
