Copper causes metallurgical problems in steel products, but is pervasive in end-of-life steel scrap and there is no commercial process to remove it from the melt. An extraction process would allow for high quality steel recycling, which becomes increasingly attractive as the end-of-life scrap supply expands [see Daehn et al, ES&T 2017]. There have been dispersed laboratory investigations to chemically extract copper from steel. We provide a systematic framework to define the range of possible separation mechanisms and operating parameters, in which past experimental work is catalogued. Governing thermodynamic and kinetic equations, as well as models of reactor equipment are used to evaluate the feasibility of separation routes and estimate the energy, time and material inputs required to remove copper from the typical contaminated copper concentration (0.4 wt%) to the concentration allowing for the production of flat products (0.1 wt%).
