Abstract

PROCEDE D'EXTRACTION DU NICKEL PAR LIXIVIATION A L'AIDE D'ACIDE SULFURIQUE DANS UN REACTEUR 6. LA SUSPENSION PRODUITE ET SE COMPOSANT DE SULFATES DE NICKEL, DE MAGNESIUM ET DE FER DISSOUS ET DE SUBSTANCES NON DISSOUTES EST ENVOYEE DANS UNE CUVE 11 DE NEUTRALISATION. LE NICKEL ET D'AUTRES METAUX LOURDS SONT ENSUITE SEPARES. LA SOLUTION CONTENANT LE SULFATE DE MAGNESIUM EST CONCENTREE PAR EVAPORATION AVEC SEPARATION D'EPSOMITE A L'ETAT CRISTALLIN 23, LES CRISTAUX SONT DECOMPOSES DANS UN FOUR 28 EN OXYDE DE MAGNESIUM, ANHYDRIDE SULFUREUX ET VAPEUR D'EAU ET DE L'ACIDE SULFURIQUE EST PRODUIT A L'AIDE DE L'ANHYDRIDE SULFUREUX EN 31 PUIS EST RECYCLE DANS LE REACTEUR 6. APPLICATION A L'EXTRACTION DU NICKEL DE MINERAIS LATERITIQUES.
