Abstract
LA INVENCION SE REFIERE A UN METODO PARA LA REDUCCION DE MINERALES METALICOS QUE IMPLICA UN PROCESO COMBINADO, EN EL QUE LOS MINERALES METALICOS SON REDUCIDOS PARCIALMENTE EN UNA O MAS ETAPAS Y A CONTINUACION REDUCIDOS POR COMPLETO A METAL EN UN REACTOR DE BAJA FUSION. EL PROCESO COMBINADO COMPRENDE POR LO MENOS TRES UNIDADES DE PROCESO Y EL REACTOR DE BAJA FUSION FORMA UNA UNIDAD DE PROCESO. LA REDUCCION PARCIAL DE LOS MINERALES METALICOS ES REALIZADA EN AL MENOS OTRAS DOS UNIDADES DE PROCESO. UN GAS RESIDUAL DIFERENTE ES PRODUCIDO EN CADA UNA DE ESTAS TRES UNIDADES DE PROCESO, POR LO MENOS.
