Abstract

In the refining of metals, and more particularly electrolytic copper, the metals are first heated in an electric radiating furnace to 900-1000 DEG C., so as to avoid melting whilst protecting them from the atmosphere until the major part of the occluded hydrogen has escaped, the metals being afterwards melted in the same furnace and then cast immediately while protected from the action of the atmosphere. When treating copper cathodes, they are placed on charcoal in the furnace before being heated. Other metals such as iron, cobalt nickel and aluminium may also be refined in the same manner.
