Abstract
EL INVENTO PROPONE UN PROCESO PARA PRODUCIR PLOMO ELECTROLITICO Y AZUFRE ELEMENTAL DE GALENA, CARACTERIZADO EN QUE COMPRENDE LOS SIGUIENTES PASOS: (A) LA GALENA ES LIXIVIADA CON UNA SOLUCION ACUOSA ACIDICA DE FLUOBORATO FERRICO, CON FLUOBORATO FERROSO, FLUOBORATO DE PLOMO Y AZUFRE ELEMENTAL, QUE SON FORMADOS ACORDES A LA REACCION: 2 FE(BF4)3 + PBS (BF4)2 + S (B) EL RESIDUO SOLIDO, COMPUESTO POR AZUFRE ELEMENTAL Y GANGA DE GALENA ES FILTRADO; (C) LA SOLUCION FLUOBORATO FERROSO Y FLUOBORATO DE PLOMO QUE VIENEN DEL PASO (A) SON ENVIADOS A UNA CELULA ELECTROLITICA DE DIAFRAGMA, EN DONDE EL PLOMO PURO ES DEPOSITADO EN EL CATODO, Y EN EL ANODO, EL ION FERROSO ES OXIDADO A ION FERRICO; (D) LA SOLUCION DE FLUOBORATO FERRICO REGENERADA EN EL ANODO EN DICHO PASO (C) ES RECICLADA A DICHO PASO (A) DE LIXIVIAR LA GALENA. POR OPERAR BAJO CONDICIONES CONVENIENTES, EL PLOMO PUEDE SER SELECTIVAMENTE DISUELTO Y SEPARADO DE LAS OTRAS PEQUEÑAS CANTIDADES DE METALES DE LOS QUE SON CONTENIDOS EN LA GALENA JUNTOCON DICHO PLOMO. EL AZUFRE PRODUCIDO POR LA REACCION PUEDE SER SEPARADO DE LA GANGA POR LA EXTRACCION CON UN SOLVENTE, O POR FLOTACION.
