Abstract (en)
[origin: WO2008079015A1] Method for removal of elements from a metal melt in a container, which melt contains a base metal and elements of undesirable constituents, in which the metal melt is heated to a level maintaining the content melted. The metal melt is heated to a level causing vaporization of an element to be removed, but under the level providing gas pressure for the base metal. The container with the metal melt is brought under a reduced pressure in at least one compartment in which the temperature is maintained under the vaporization level of the element to be removed. A device for the removal of elements from metal melts, with a container (1) for the metal melt, with an exit tube (5) over the level of the metal melt, for vapour from the interior of the container (1). The exit tube (5) exits into a compartment (27) which is kept at a temperature under the vaporization temperature, for condensing the vaporized metal.
