Abstract

METODO DE DISOLUCION OXIDATIVA DE SELENIO Y TELURO DE LODOS ANODICOS. COMPRENDE EL TRATAMIENTO PREVIO DE LOS LODOS ANODICOS CON UNA DISOLUCION ACIDA DE LIXIVIACION PARA SEPARAR EL COBRE; PONERLOS EN CONTACTO CON UNA DISOLUCION ACUOSA DILUIDA, DEBILMENTE ACIDA, DE PH NO SUPERIOR A 5, DE AL MENOS 2 MOLES DE PEROXIDO DE HIDROGENO POR MOL DE SELENIO Y TELURO, A UNA TEMPERATURA COMPRENDIDA ENTRE LA AMBIENTE Y LA DE REFLUJO DE LA MEZCLA, DURANTE UN PERIODO DE TIEMPO ENTRE 4 Y 10 HORAS. SEPARACION DEL LIQUIDO DE CUALQUIER SOLIDO RESIDUAL Y NEUTRALIZACION PARCIAL PARA CONSEGUIR LA PRECIPITACION DE ACIDO TELUROSO; ACIDIFICACION E INTRODUCCION DE DIOXIDO DE AZUFRE PARA REDUCIR SELENIO A SELENIO ELEMENTO CONSIGUIENDO SU PRECIPITACION. TIENE APLICACIONES PARA LA SEPARACION DE METALES EN LOS LODOS PROCEDENTES DE LA ELECTROLISIS DEL COBRE.
