A B S T R A C T The alumina linings of electrolytic reduction calls become contaminated with carbides, nitrides and fluorides with continued use of the cell. A procedure for the recovery of such used alumina linings comprises subjecting the crushed used lining to the action of dry steam in a pressure vessel to effect break down and removal of carbides and nitrides. The thus treated material, which is partially hydrated, is then charged to the electrolyte of an electrolytic reduction cell to recycle both the fluoride and alumina content of the used alumina lining.
