科研成果: Patent

摘要

FIELD: metallurgy. SUBSTANCE: invention relates to the problem of aluminum electrolysis slimes recycling. Method involves washing slimes with water, drying and oxidizing firing to produce secondary raw material for aluminum production. In slimes washing, hydrolysed polyacrylamide-based flocculant is used in pulsation column apparatus operating in ideal displacement mode. EFFECT: method enables higher flocculated solid phase washing from sulphate ion.
