METHOD AND APPARATUS FOR RETRIEVING METALLIC VAPOR IN THE LIQUID PHASE USING POOL OF MOLTEN RETRIEVING METAL ABSTRACT OF THE DISCLOSURE A mixture gas containing metallic vapor with oxidizing gas produced by reducing of the oxide of the metal at high temperature is led, at a high enough temperature and a low enough pressure for the reverse oxidization reaction between them to not substantially take place, into a convergent- divergent nozzle, and squirts out from the nozzle, as cooled down rapidly by adiabatic expansion in the nozzle to a low enough temperature for the oxidization reaction between them to not substantially take place, to be led to the surface of a pool of molten retrieving metal, either directly or via deceleration. The retrieving pool metal may be the same kind as the metallie vapor to be retrieved, or may be different. When the metallic vapor to be retrieved is magnesium vapor, the retrieving metal of the different kind may be lead, bismuth, tin, antimony, or a mixture thereof.
