Abstract
SE SOMETE UN MINERAL DE OXIDO METALICO A UNA REDUCCION POR FUSION PARA OBTENER EL METAL FUNDIDO POR UN METODO QUE COMPRENDE LA PRERREDUCCION DE DICHO MINERAL EN ESTADO SOLIDO EN UN HORNO DE PRERREDUCCION (1) DESPUES DE ESTO SE FUNDE DICHO MINERAL REALIZANDO LA REDUCCION FINAL EN UN HORNO DE REDUCCION (2), Y AL MISMO TIEMPO INTRODUCIENDO GAS GENERADO EN DICHO HORNO DE REDUCCION POR FUSION (2) Y QUE TIENE CAPACIDAD REDUCTORA EN EL CITADO HORNO DE PRERREDUCCION (1). EL METODO ESTA CARACTERIZADO POR LA VELOCIDAD DE PRERREDUCCION DEL MINERAL EN EL HORNO DE PRERREDUCCION DEL MINERAL EN EL HORNO DE PRERREDUCCION (1) QUE ESTAQ CONTROLADA A UN VALOR CON UN MAXIMO DEL ORDEN DEL 33% PARA ELEVAR LA VELOCIDAD DE UTILIZACION A UN LIMITE MAXIMO.
