Abstract

PROCEDE DE TRAITEMENT DE MINERAIS URANIFERES. ON IMPREGNE LE MINERAI BROYE PAR UNE SOLUTION CONCENTREE D'ACIDE SULFURIQUE, LE VOLUME INITIAL DE SOLUTION APPORTE PAR UNITE DE MASSE DE MINERAI ETANT CHOISI POUR OBTENIR UN PRODUIT AYANT UNE CONSISTANCE SOLIDE ET LA TENEUR EN ACIDE SULFURIQUE ETANT TELLE QUE L'ON OBTIENNE UNE ACIDITE RESIDUELLE EN FIN D'ATTAQUE EN PULPE COMPRISE ENTRE 10GL ET 40GL; APRES IMPREGNATION PENDANT UNE DUREE NE DEPASSANT PAS 30 MINUTES, LE PRODUIT EST DELITE PAR UNE SOLUTION AQUEUSE EN PULPE EPAISSE DANS LAQUELLE ON POURSUIT L'ATTAQUE PENDANT UNE DUREE NE DEPASSANT PAS 10 HEURES, AFIN DE FINIR DE SOLUBILISER L'URANIUM AVANT SEPARATION SOLIDE-LIQUIDE. APPLICATION AUX MINERAIS REFRACTAIRES A L'ATTAQUE DIRECTE EN PULPE PAR DES SOLUTIONS SULFURIQUES.
