Abstract

Se describe un proceso para separar el plomo de la espuma a la que se ha separado el bismuto, en donde la espuma se trata primero para separar el calcio y el magnesio, y luego la espuma beneficiada se copela para formar una escoria la cual es espuma partir de la espuma copelada resultante, se deja la espuma copelada con un nivel de bismuto más alto, el cual proceso está caracterizado porque se lleva a cabo la etapa de copelación hasta el nivel de bismuto de la espuma copelada alcanza la cantidad de hasta aproximadamente 45 de peso.
