Abstract
According to the present method it is possible to recover metallic aluminium easily and at high recovery rate and low cost from metallic aluminium containing wastes disposed recently in great amounts, said wastes being, for example, aluminium can, aluminium laminated foil, aluminium scraps, aluminium chips, and any other aluminium containing (or accompanying) material. The invention is technically constituted such that the combustible substances of metallic aluminium containing materials are carbonized in a kiln in an atmosphere where oxygen concentration is not higher than 10% by volume or an atmosphere of a carbon dioxide gas, and which kiln is in the temperature range of 300.degree.-600.degree. C., and after cooling, carbonized material and iron content are separated by sieving or magnetically.
