Abstract

L’invention consiste à recycler puis épurer, par une cascade de nanofiltrations en boucle fermée, de l’acide sulfurique de régénération de résine échangeuse d’ions et de concentrer ainsi l’uranium initialement contenu dans celui-ci, en vue de sa récupération sous forme de peroxyde d’uranyle. L’acide sulfurique soumis à nanofiltration est issu du traitement de phosphates naturels avec ce dernier.The invention consists of recycling then purifying, by a cascade of closed-loop nanofiltrations, sulfuric acid from the regeneration of ion exchange resin and thus concentrating the uranium initially contained therein, with a view to its recovery in the form of uranyl peroxide. The sulfuric acid subjected to nanofiltration comes from the treatment of natural phosphates with the latter.
