Obtaining metal alloys of iron and slag from the Aluminothermic processing of industrial solid waste is the purpose of this study. Seven mixtures were obtained by using a Mc Lean Anderson experimental design, where the amount of aluminum varied from 33 to 45 g, the ash 0 to 20 g, the graphite from 0 to 4 g, keeping the lamination scale in 100 g. The performance of the process in terms of quantity and efficiency of metal and slag was evaluated; As a result, the three best alloy mixtures were selected whose carbon content was between 1.33 - 3.62%, silicon of 0.24 - 0.96%, manganese between 0.41 - 0.78% of aluminum and between 0.2 - 11%, and a group of high-value alloy elements (Mn, Cr, Mo, Ni, V, Ti, Nb, Co and W). The technical feasibility of the aluminothermic processing of this industrial waste allows recovering its metallic components, which guarantees the use of these alloys in the industry, while reducing the levels of environmental contamination.Downloads
