ABSTRACT OF THE DISCLOSURE The disclosure teaches an improvement in the degassing and filtration of molten metal, especially aluminum, using an apparatus which employs a pair of sequentially placed, removable filter-type plates and at least one fluxing gas inlet positioned therebetween. Fluxing gas is provided to the melt trough the inlet and flows upward through the first of said plates into counter-current contact with the melt. Said plate serves to break up said fluxing gas into a fine dispersion to assure its intimate and extensive contact with the molt. Dissolved gases and non-metallic inclusions are thereby abstracted and removed from the melt.
