    Innovations: Overview of Recycled Copper

    The liquid copper can be fed to the next process step by means of a ladle or launder. The hearth-shaft furnace is additionally equipped with a hearth for holding, deslagging, and further treatment of the liquid copper. Thus, scrap of low quality can also be used. The molten copper is transferred via launders to refining furnaces.
