Abstract

DONDE MATERIALES CRUDOS SILICEOS SON LLEVADOS A LIXIVIACION ACIDA CONTINUA CON UNA SOLUCION DE ACIDO SULFURICO, CON LO QUE LOS SILICATOS EN DICHO MATERIAL SE DESCOMPONEN, DISUELVEN Y PRECIPITAN EN FORMA DE SILICE, SIENDO DISMINUIDO EL CONTENIDO DE ACIDO DURANTE LA LIXIVIACION, DE MODO QUE EL pH DE LA SOLUCION AL FINAL DE LA LIXIVIACION ES DE 1,5 A 2. LA TEMPERATURA DE LIXIVIACION ES ENTRE 60°C Y 100°C, Y HAY NUCLEOS DE SILICE EN LA SOLUCION AL FINAL DE LA LIXIVIACION. LA LIXIVIACION COMPRENDE ALIMENTAR EL MATERIAL CRUDO A UNA ETAPA DE LIXIVIACION NEUTRAL, DONDE LOS COMPUESTOS DE ZINC FACILMENTE SOLUBLES EN EL MATERIAL CRUDO SE DESCOMPONEN OBTENIENDO UNA SOLUCION DE SULFATO DE ZINC QUE ES LLEVADA A ELECTROLISIS Y LUEGO A LIXIVIACION ACIDA EN VARIOS REACTORES EN LOS QUE EL pH DE LA SOLUCION SE ELEVA EN DIRECCION DEL FLUJO PRODUCIDO EN EL REACTOR FINAL
