Abstract

Le procédé selon l'invention comporte le refroidissement des crasses en fusion dans un moule sous une température inférieure à environ 420 degrés C pour obtenir un lingot de crasses sensiblement à l'état solide, le réchauffage du lingot sur le support perméable à une température de 420 à 700 degrés C, et le maintien de l'intégrité du lingot pendant la séparation du zinc par fusion.
