Abstract
SE REVELA UN PROCESO Y UN APARATO PARA LA RECUPERACION DE METALES NO FERROSOS PREFERIBLEMENTE ALUMINIO Y ALEACIONES DE ALUMINIO DE FORMA FUNDIDA COHERENTE A PARTIR DE UNA CARGA DE MATERIAL QUE VA A SER PROCESADO QUE CONTIENE EL METAL. LA CARGA ES INTRODUCIDA EN UN HORNO HERMETICO EL CUAL ES DESPUES SELLADO. LA CARGA ES AGITADA. UN PARAMETRO DE CONTROL INDICATIVO DE LAS CONDICIONES EN EL INTERIOR DE DICHO HORNO ES CONTROLADO Y COMPARADO CON UNA PRIMERA CONDICION PREDETERMINADA PARA EL PARAMETRO. UNA FUENTE DE CALOR ES ACCIONADA PARA CALENTAR LA CARGA HASTA QUE EL PARAMETRO DE CONTROL ALCANZA LA PRIMERA CONDICION. DESPUES SE PARA EL ACCIONAMIENTO DE LA FUENTE DE CALOR. UNA CANTIDAD CONTROLADA DE AGENTE OXIDANTE Y UN PORTADOR INERTE ES DESPUES INTRODUCIDO DENTRO DEL HORNO. EL PARAMETRO DE CONTROL ES CONTROLADO Y COMPARADO CON UNA SEGUNDA CONDICION PREDETERMINADA PARA EL PARAMETRO. EL FLUJO DE AGENTE OXIDANTE Y DEL PORTADOR ES CONTROLADO PARA MANTENER EL PARAMETRO DE CONTROL EN APROX. LA SEGUNDA CONDICION. EL METAL FUNDIDO ES POSTERIORMENTE ELIMINADO DEL HORNO.
