Abstract

L'INVENTION A TRAIT AU TRAITEMENT D'UN MINERAI D'URANIUM. ELLE CONCERNE UN PROCEDE DE NEUTRALISATION D'UNE LIQUEUR RESIDUAIRE EN VUE DE RECYCLER L'EAU DANS LE TRAITEMENT D'UN MINERAI D'URANIUM, CARACTERISE PAR LE FAIT QUE LA LIQUEUR RESIDUAIRE EST TOUT D'ABORD NEUTRALISEE DANS LA PLAGE DE TEMPERATURES DE 15 A 80C AVEC UN LEGER EXCES DE CHAUX, JUSQU'A CE QUE SON PH AIT UNE VALEUR DE 9 A 10, PUIS LE FER ET LE MANGANESE DIVALENTS SONT OXYDES PAR PASSAGE D'AIR ET FINALEMENT, L'EAU TRAITEE EST SEPAREE DU PRECIPITE ET REUTILISEE DANS LE PROCEDE DE TRAITEMENT DU MINERAI D'URANIUM. LE PROCEDE DE L'INVENTION REDUIT LES RISQUES DE POLLUTION DE L'ENVIRONNEMENT.
