Abstract
a. Procédé d'extraction du cadmium des céments cadmifères. b. Les céments cadmifères obtenus selon le procédé d'extraction électrolytique du zinc, sont séchés, et soumis à un lessivage avec une solution neutre de sulfate de zinc. La solution est traitée ensuite par électrolyse. c. Le procédé permet d'éliminer les opérations supplémentaires de dépuration, étant donnée l'absence absolue de Fe, Cu et Pb dans la solution obtenue en milieu neutre En outre, est évité tout développement d'hydrogène et d'hydrogène arsénical. Finalement les rendements obtenus sont plus élevés qu'avec les procédés connus.
