Abstract

L'INVENTION CONCERNE L'EXTRACTION DE L'OXYDE CHROMIQUE D'UNE SOLUTION CONTENANT DU CHROME. LE PROCEDE CONSISTE A PARTIR D'UNE SOLUTION DE NACRO OU NACRO, A PRODUIRE LE COMPOSE (NH)CRO PAR EXTRACTION AU SOLVANT, A EVAPORER LA SOLUTION AQUEUSE DE (NH)CRO ET A CALCINER LA MATIERE SOLIDE RESULTANTE POUR OBTENIR UN OXYDE CHROMIQUE CRO DE GRANDE PURETE. APPLICATION AU TRAITEMENT DE MINERAIS DE CHROME.THE INVENTION RELATES TO THE EXTRACTION OF CHROMIC OXIDE FROM A SOLUTION CONTAINING CHROME. THE PROCESS CONSISTS OF STARTING WITH A NACRO OR NACRO SOLUTION, PRODUCING THE (NH) CRO COMPOUND BY SOLVENT EXTRACTION, EVAPORATING THE AQUEOUS SOLUTION OF (NH) CRO AND CALCINING THE RESULTING SOLID MATERIAL TO OBTAIN A CHROMIC CRO OXIDE IN GREAT PURITY. APPLICATION TO THE PROCESSING OF CHROME ORE.
