Use of auto shredder residues generated by post shredder technology in metallurgical furnace

Abstract : The whole objective of the presented work is to define further sequences of separation processes to meet the requirement associated with a use in metallurgical furnaces of these two fractions, as reducing agents and recycled material respectively. This paper will present the results of chemical and mineralogical characterization of fractions sampled on an industrial line of treatment of automotive residues. The results feed two mass balance models of a blast furnace and an electric arc furnace, to determine the amount of each fractions injectable in both furnaces considering the requirements for a smooth processing of a high-quality pig iron. Two global processes of separation, each dedicated to a given fraction, are also defined with the aim at increasing the quantity introduced in the furnaces.
