Abstract

LA INVENCION SE REFIERE A UN METODO PARA RECUPERAR LOS METALES FERROSOS DE UN MATERIAL INICIAL DE ESCORIA QUE CONTIENE ESTE METAL, JUNTO CON, OPCIONALMENTE, METAL VIEJO NO FERROSO, Y/O UN MATERIAL INICIAL QUE CONTENGA TAL METAL VIEJO. EL METODO CONSISTE EN INTRODUCIR EL MATERIAL INICIAL EN UN HORNO ROTATIVO O EN UN CONVERSOR ROTATIVO QUE TENGA UN REVESTIMIENTO REFRACTARIO, CALENTAR EL MATERIAL INICIAL A UNA TEMPERATURA SUPERIOR AL PUNTO DE FUSION DEL METAL AL TIEMPO QUE SE HACE ROTAR AL HORNO BIEN DE FORMA CONTINUA O INTERMITENTE Y RETIRAR EL METAL FUNDIDO RESULTANTE DE DEBAJO DE LOS RESIDUOS DE LA ESCORIA SUPERPUESTOS. EL METODO SE CARACTERIZA PORQUE EL CALENTAMIENTO DEL MATERIAL INICIAL SE LLEVA A CABO EN AUSENCIA DE UNA CAPA PROTECTORA DE SAL CON LA AYUDA DE LO QUE SE DENOMINA UN OXIQUEMADOR DE COMBUSTIBLE QUE SE SUMINISTRA CON UN COMBUSTIBLE FOSIL Y CON UN GAS QUE CONTENGA UN 80% DE OXIGENO POR LO MENOS Y A BASE DE HACER ROTAR AL HORNO A UNA VELOCIDAD DE 5 RPM O MENOR.
