Abstract
Perfeccionamientos en, o relativos a, la separación de plomo y zinc desde mezclas de los mismos, caracterizados porque para separar zinc puro desde zinc de bajo contenido en plomo se destila bajo vacío el zinc conteniendo plomo a temperaturas desde alrededor de 450 hasta 500ºC, con lo que el vapor obtenido está prácticamente libre de plomo.
