Abstract

Procedure for the separation of fluorine, aluminum and sodium compounds from furnace residues for the production of aluminum by melt electrolysis, characterized in that the crushed furnace residues are leached with an alkaline solution from which the fluorine compounds are precipitated, aluminum and sodium in the form of double fluorides in a two-stage precipitation process, the first of which takes place in a basic medium while the second takes place in an acid medium.
