2020-5-6 grinding has been evaluated using three different scrap aluminum products: cable wastes, shavings and aluminum sheet pieces. The chemical composition of the cable scrap and the shavings have been determined by semi-quantitative spectral assay. The results obtained are presented in Table 3. Table 3 : The results front the semi - yudiititive spectral assay
