Abstract

Perfectionnement au procédé selon la revendication principale. Ce perfectionnement est caractérisé par le fait que ledit produit de départ contient du plomb et par le fait que le plomb mis en solution est récupéré sous forme de chlorure de plomb cristallisé, lequel chlorure de plomb est ensuite fondu, puis réduit au moyen d'hydrogène. Application à la métallurgie du plomb.
