Abstract

La présente invention concerne un procédé de fabrication de sulfate de sodium à partir de phosphogypse, comprenant: - une étape (101) de lixiviation du phosphogypse au moyen d'une solution basique de sorte à obtenir une solution (S) de sulfate de sodium contenant des impuretés métalliques, ladite solution basique comprenant un agent chélateur adapté pour former des complexes avec au moins une partie desdites impuretés métalliques, - au moins une première étape (103, 104) de filtration de la solution de sulfate de sodium par une membrane de nanofiltration (NF1, NF2), de sorte à former un concentrat (C1, C2) contenant lesdits complexes et un perméat (P1, P2), - une étape (105) d'évaporation du perméat (P1, P2) de sorte à former du sulfate de sodium anhydre.
