Abstract
A method of removing skim from molten metal comprises providing a body of molten metal and passing a fluxing gas therethrough to carry skim to the surface of the metal. The skim on the surface is treated to substantially reduce the amount of molten metal contained therein and to provide the skim in a substantially powdery form. A portion of the treated skim in finely divided form is removed to a collector.
