  • Process for producing solid metal particles from a bath of metal
    Patent number: 4518421
    Abstract: The process concerns a selective refining of molten metals or alloys contained in a closed treatment container in the form of a bath 10. A solid or liquid cryogenic body 13 is brought into contact with the surface of the bath of metal 10 so as to convert, by evaporation-condensation, the vapors (vz) of the impurity or impurities to be eliminated from the bath into solid particles (pz) entrained by the vapors (vf) of the cryogenic body, and the bath of metal 10 is simultaneously stirred.
