Abstract

Layers of substantially solid fine-grained material formed on a molten-lead bath, e.g. in the refining of lead and consisting substantially of copper dross, are removed in accordance with the invention by pneumatic evacuation of the layers after they have been loosened mechanically or pneumatically, e.g. by a beater or an air blast.
