Recyclability of technology metals from E-waste: Case study of in and Ga recovery from magnetic fraction
Abstract
This study presents the results of the theoretical assessment and a preliminary experimental investigation of technology metals (TM) recovery from magnetic fraction obtained after mechanical treatment of waste printed circuit boards (WPCBs). Experimental work included physical and chemical characterization, thermodynamic analysis, and pyrometallurgical tests corresponding to secondary lead, copper, and steel metallurgy. Technology metals recyclability and recovery potential were evaluated with respect to their distribution between metal and slag phase (difficult for recovering) versus the dust phase (easy for recovering). According to obtained results, it was determined that high-temperature processing of magnetic fraction in the electric arc furnace promotes volatilization of the TM and their pre-concentration in the filter as a dust product from which they could be valorized using further hydrometallurgical methods. © 2019, Association of Metallurgical Engineers of Serbia.
