- 1 - METHOD AND APPARATUS FOR LIQUID METAL COLLECTION FROM VAPOR USING MOLTEN POOL OF COLLECTING METAL ABSTRACT OF THE DISCLOSURE A metal vapor, such as can be produced by sublimation of crudely smelted lumps of the metal at high temperature, is led, at a high enough temperature and a low enough pressure for the condensation of the vapor not to take place, into the upstream end of a convergent-divergent nozzle, and then squirts out from this nozzle, being cooled down rapidly by adiabatic expansion in the nozzle to a low enough temperature for the condensation of the vapor to take place. The jet flow emitted from the downstream end of the convergent-divergent nozzle, which has been thus cooled, is led to the surface of a pool of molten collecting metal, either directly or via a jet flow decelerating device. The collecting metal in this collecting metal pool is the same kind of metal as the metal vapor which is to be collected. Thus the condensed metal vapor in the jet flow is entrained into the collecting metal pool in the liquid state. Apparatuses are also disclosed for performing these various methods.
