USE OF ALUMINA-CARBON AGGLOMERATES IN THE CARBOTHERMIC PRODUCTION OF ALUMINUM

摘要

An agglomerate, comprising alumina, carbon, and a binder for use in a vapor recovery reactor of a carbothermic alumina reduction furnace is disclosed. A method for using alumina-carbon agglomerates to capture aluminum vapor species and utilize waste heat from off-gases in a vapor recovery reactor to form a recyclable material is also disclosed. The recyclable material formed typically comprises aluminium carbide and Al-carbide containing slag, which are recycled to the carbothermic reduction furnace.
