The influence of the salt quantity on the recovery yield of aluminium scrap was studied considering an heterogeneous charge. The analysed heterogeneous charge was composed by different types of scrap such as turning, shredded materials and dross. The amount of salt was related to the scrap quality using the salt factor, which is defined as the ratio between the non-aluminium content in the scrap and the quantity of salt required. Two levels of salt factor were considered, 1.2 and 1.8. The analysis of variance was then implemented to verify the influence of the salt quantity on the recovery yield. The results were statistically confirmed using the Anderson-Darling test, the Dixon’s outliers test and the coefficient of variance. An increment of the recovery yield from 95% to 97% was revealed by increasing the salt factor from 1.2 to 1.8.

Abstract

The influence of the salt quantity on the recovery yield of aluminium scrap was studied considering an heterogeneous charge. The analysed heterogeneous charge was composed by different types of scrap such as turning, shredded materials and dross. The amount of salt was related to the scrap quality using the salt factor, which is defined as the ratio between the non-aluminium content in the scrap and the quantity of salt required. Two levels of salt factor were considered, 1.2 and 1.8. The analysis of variance was then implemented to verify the influence of the salt quantity on the recovery yield. The results were statistically confirmed using the Anderson-Darling test, the Dixon’s outliers test and the coefficient of variance. An increment of the recovery yield from 95% to 97% was revealed by increasing the salt factor from 1.2 to 1.8.
