Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA ELIMINAR IMPUREZAS DEL SILICIO FUNDIDO MEDIANTE EL TRATAMIENTO DEL SILICIO FUNDIDO (4) CONTENIDO EN UN VASO (2) CON UNA ESCORIA (5) QUE TENGA LA CAPACIDAD DE ELIMINAR LAS IMPUREZAS, PARTICULARMENTE EL BORO, DEL SILICIO FUNDIDO. LA ESCORIA (5) SE AÑADE DE FORMA CONTINUA O SUBSTANCIALMENTE CONTINUA AL SILICIO FUNDIDO (4) Y ENTONCES SE INACTIVA O SE SEPARA DEL SILICIO FUNDIDO (4) DE FORMA CONTINUA O SUBSTANCIALMENTE CONTINUA A MEDIDA QUE SE ALCANCE EL EQUILIBRIO ENTRE LA ESCORIA (6) Y EL SILICIO FUNDIDO (4) CON RESPECTO A LOS ELEMENTOS DE IMPUREZA O A LOS ELEMENTOS A ELIMINAR.
