Abstract
DONDE LOS SULFUROS POLIMETALICOS ESTAN CONTENIDAS EN UNA MENA QUE ADEMAS CONTIENE Fe, Al, Cr, Ti, Cu, Zn, Pb, Ni, Co, Hg, Sn Y MEZCLAS DE LOS MISMOS. DICHA RECUPERACION CONSISTE EN: a) TRITURAR LA MENA POLIMETALICA PARA PRODUCIR GRANULOS; b) OXIDAR LOS GRANULOS A TEMPERATURAS DE POR LO MENOS 300°C PARA PRODUCIR GRANULOS OXIDADOS; c) LIXIVIAR CON UNA SOLUCION DE SALMUERA LOS GRANULOS OXIDADOS PARA PRODUCIR UNA SOLUCION IMPREGNANTE DE CLORUROS DE METAL SOLUBILIZADOS Y UN SOLIDO IMPRODUCTIVO; d) RECUPERAR COMO FILTRADO EL SOLIDO IMPRODUCTIVO DE LA SOLUCION IMPREGNANTE, LAVANDO CON UNA SOLUCION DE SALMUERA PARA PRODUCIR LAVADOS Y UN SOLIDO ESTERIL, LUEGO DE LO CUAL LOS LAVADOS SE COMBINAN CON EL FILTRADO PARA PRODUCIR UNA SOLUCION IMPREGNANTE PURIFICADA; e) TRATAR LA SOLUCION IMPREGNANTE PURIFICADA CON CARBON ACTIVADO PARA RECUPERAR ORO Y/O PLATA, Y PRODUCIR UNA SOLUCION SIN ORO Y/O PLATA; Y, f) TRATAR LA SOLUCION SIN ORO Y/O PLATA CON UNA SOLUCION CAUSTICA PARA PRODUCIR UNA PRIMERA MEZCLA DE REACCION CON pH DE 2,5 A 3,5, UN PRECIPITADO QUE COMPRENDE COMPUESTOS DE OXIDOS DE METAL HIDRATADOS CON Fe, Al, Cr Y Ti, Y UNA PRIMERA SOLUCION SIN DICHOS METALES. LA PRIMERA SOLUCION SE TRATA CON UNA SOLUCION CAUSTICA PARA PRODUCIR UNA SEGUNDA MEZCLA DE REACCION CON pH DE 3,5 A 14,UN PRECIPITADO QUE INCLUYE COMPUESTOS DE OXIDOS DE METAL HIDRATADOS TALES COMO Ni, Cu, Co, Zn, Pb Y Sn, Y UNA SEGUNDA SOLUCION SIN DICHOS METALES
