Abstract

PROCEDIMIENTO HIDROMETALURGICO PARA EL TRATAMIENTO DE POLVOS QUE CONTIENEN ZINC, PROCEDENTES DE HORNOS DE CRIAS ELECTRICAS. COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, SE SOMETE A UNA PRIMERA LIXIVIACION EL OXIDO DE ZINC CON UNA CONCENTRACION RELATIVAMENTE BAJA EN SOSA ACUSTICA; SEGUNDA, SE SOMETE A UNA SEGUNDA LIXIVIACION LA FERRITA DE ZINC CON UNA CONCENTRACION MAS ELEVADA EN SOSA CAUSTICA; Y POR ULTIMO, SE EXTRAE EL ZINC DE LA SOLUCION OBTENIDA EN LA SEGUNDA FASE. LA LIXIVIACION DEL OXIDO DE ZINC SE EFECTUA CON UNA CONCENTRACION EN SOSA DE 250 GRAMOS, A UNA TEMPERATURA COMPRENDIDA ENTRE 95 Y 105 GRADOS, Y DURANTE UN TIEMPO APROXIMADO DE CUATRO HORAS.
