Title (EN) MAGNETIC SEPARATION PROCESS FOR BENEFICIATING SULFIDE ORES
(FR) PROCEDE DE SEPARATION MAGNETIQUE POUR LA PREPARATION MECANIQUE DES MINERAIS SULFUREUX
Abstract: front page image
(EN)A process for beneficiating one or more mineral values of sulfide and oxide ores by treating the ore with a metal-containing compound under conditions such as to selectively enhance the magnetic susceptibility of the mineral values to the exclusion of the gangue in order to permit a separation between the values and gangue, and improvements comprising: pretreating the ore by heating it to a temperature of at least about 80 C for at least about 0.1 hours; removing any elemental sulfur present in the ore by preheating or solvent extraction prior to treating the ore with the metal-containing compound; cotreating the ore with a reducing gas while preheating, or while treating with the metal-containing compound.
(FR)Procede de preparation mecanique d"une ou plusieurs valeurs de minerais de sulfure ou d"oxyde en traitant le minerai avec un compose metallifere sous certaines conditions de maniere a ameliorer selectivement la susceptibilite magnetique des valeurs minieres a l"exclusion de la gange de maniere a permettre une separation entre les valeurs et la gange, et amelioration consistant a pretraiter le minerai en le chauffant a une temperature d"au moins 80 environ pendant au moins 0,1 heure; a enlever tout sulfure elementaire present dans le minerai par prechauffement ou extraction au solvant avant le traitement du minerai avec le compose metallifere; a traiter le minerai avec un gaz de reduction tout en prechauffant, ou pendant le traitement avec le compose metallifere.
