FIELD: mining.
SUBSTANCE: invention relates to alumina-carbon agglomerates for vapor recovery reactor in furnace for carbo-thermic reduction of alumina. Agglomerate is composed in form of cylinder containing hollow core, and containing source of alumina and shell containing source of carbon and binder. Disclosed is method for application of alumina-carbon agglomerates to recovery of aluminium-containing vapor components, and useful use of waste heat of exhaust gases in vapor recovery reactor for formation of recyclable material. Formed recyclable material contains aluminium carbide and Al carbide containing slag, which are recirculated into carbo-thermic reduction furnace.
EFFECT: catching of aluminium-containing vapor components is simplified, and flow limitation is achieved of obtained recirculated material, containing aluminium carbide, in carbo-thermic furnace for aluminium production.
