PROCEDE D'ENRICHISSEMENT DE MINERAIS DE CUIVRE OXYDES DIFFICILEMENT ENRICHISSABLES

The method provides for preparation of a pulp, its sulphidizing and floatation. The sulphidizing of the pulp is effected with melted sulphur at a temperature of 115-180 DEG C and at a pressure of 1.5-10 atm in the presence of sodium sulphate or sodium chloride at a mass ratio between the sulphur and...

Zusammenfassung:	The method provides for preparation of a pulp, its sulphidizing and floatation. The sulphidizing of the pulp is effected with melted sulphur at a temperature of 115-180 DEG C and at a pressure of 1.5-10 atm in the presence of sodium sulphate or sodium chloride at a mass ratio between the sulphur and the oxidized copper of (0.2-1.5):1. L'INVENTION CONCERNE LA METALLURGIE DES METAUX NON FERREUX, ET PLUS SPECIALEMENT UN PROCEDE D'ENRICHISSEMENT DE MINERAIS DE CUIVRE OXYDES DIFFICILEMENT ENRICHISSABLES.LE PROCEDE COMPORTE LA PREPARATION D'UNE PULPE, SA SULFURATION ET SA FLOTTATION. LA SULFURATION DE LA PULPE EST EFFECTUEE PAR DU SOUFRE FONDU UNE TEMPERATURE DE 115 A 180C ET UNE PRESSION DE 1,5 A 10ATM. LA SULFURATION PEUT ETRE OPEREE EN PRESENCE DE SULFATE OU DE CHLORURE DE SODIUM.L'INVENTION PEUT TROUVER DES APPLICATIONS EN METALLURGIE DES METAUX NON FERREUX POUR L'OBTENTION DU CUIVRE ET DE PRODUITS DE VALEUR ASSOCIES, NOTAMMENT L'ARGENT.
