Recycling and Dissipation of Metals: Distribution of Elements in the Metal, Slag, and Gas Phases During Metallurgical Processing

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

This chapter presents chemical thermodynamic analysis on the distribution of elements in metal, slag, and gas during metallurgical processing to discuss the recycling and dissipation of metals. This study shows the thermodynamic features of various elements in the pyrometallurgical process, and the results of the present work can give an answer to the frequent question, "Which impurity elements can be removable in the metallurgical process?" Metal recycling is expected to promote efficient use of resources. However, open-loop metal recycling systems, which are currently used to recover metals from EoL electronic products and cars, could result in material, quality, and dilution losses. Thermodynamic analysis can assist in product design by determining which metals can be metallurgically removed from natural and secondary resources. The element radar chart, which indicates how metals are separated in different carrier metal processes, graphically represents the distribution tendencies of elements in metallurgical processes.
