METHOD OF RECYCLING OF ALUMINIUM FOIL Russian patent published in 2008 - IPC C22B7/00 

Abstract RU 2336342 C1

FIELD: chemistry.

SUBSTANCE: invention relates to field of chemical technology and can be used for recycling wastes of vignetted aluminium foil. Method of foil wastes recycling includes, chopping, processing with chemical reagent solution - 3-15% solution of sulfuric acid at 65-90°C in absence of contact with air and with removal of hydrogen, released during processing, separation of interaction products by means of filtration, cooling and crystallisation of liquid phase until crystal hydrates of aluminium sulfate are obtained, weight ratio of sulfuric acid to aluminium contained in recycles mass, constitutes (5.4-6):1. Production of cellulose, crystal eighteen-water aluminium sulfate and hydrogen are ensured in explosion-safe process.

EFFECT: ensuring production of cellulose, crystal eighteen-water aluminium sulfate and hydrogen in explosion-safe process.
