Presentation Title SPG-2: Decopperization Study for Steel Recycling

On-Site Speaker (Planned) Hyunsoo Jin
Abstract Scope In recycled steel, copper-induced surface distortion and defects cause loss in ductility. Therefore, the usage of recycled steel is inversely proportional to the increase in copper content of waste steel scrap. Several lab-scale trials have been conducted to expand the field. However, the dilution method is the most efficient way these days where copper-bearing steel scrap is mixed with purer sources of iron. In the future, more electric vehicles and appliances will increase the copper contents in the waste. Thus, dilution has limitations in the future. In this study, the pyrometallurgy methods are conducted to check the feasibility to substitute dilution method. To be specific, the aluminum bath extracting method and the sulfide slagging method are selected because both can get sellable byproducts. The experiment have been carried out at ambient pressure condition and at low temperature (under 1000C) to focus on the economical side of adopting these methods.
