Abstract
DONDE LA PLATA EN BARRAS CONTIENE MAS DE 90% DE Ag, E IMPUREZAS COMO Se, Pb, Au, Cu Y METALES DEL GRUPO DEL PLATINO (MGP). EL PROCESO COMPRENDE: a) ELIMINAR DE LA FASE METALICA FUNDIDA Se, EN FORMA DE SeO2 GASEOSO, POR INYECCION DE AIRE RICO EN O2, A UNA TEMPERATURA ENTRE 1000°C Y 1100°C; b) SANGRAR Pb EN LA ESCORIA, POR CONTACTO DE LA FASE METALICA FUNDIDA CON UN FUNDENTE BASADO EN SILICE Y BORAX, A UNA TEMPERATURA ENTRE 1000°C Y 1150°C; c) GRANULAR EN AGUA LA FASE METALICA FUNDIDA, PARA FORMAR GRANULOS RICOS EN Ag; d) LIXIVIAR LOS GRANULOS RICOS EN Ag CON HNO3 A UNA TEMPERATURA SUPERIOR A 50°C, EN UNA ATMOSFERA RICA EN O2, Y LUEGO FILTRAR, SEPARANDO UN RESIDUO QUE CONTIENE Au DE UN LIQUIDO RICO EN Ag; e) CALENTAR EL LIQUIDO RICO EN Ag, PARA EVAPORAR EL H2O Y FORMAR UNA MASA FUNDIDA QUE CONTIENE AgNO3; f) MANTENER LA MASA FUNDIDA QUE CONTIENE AgNO3 A UNA TEMPERATURA ENTRE 220°C Y 350°C DURANTE AL MENOS 15 MINUTOS, PARA FORMAR UNA MEZCLA DE AgNO3 PURIFICADO Y UN RESIDUO DE DESNITRACION QUE CONTIENE ESENCIALMENTE MGP EN FORMA DE OXIDOS; Y, g) SEPARAR AgNO3 PURIFICADO DEL RESIDUO DE DESNITRACION
