Recovery of Metals from EAF Dust with Rapid System
The dust generated from the electric arc furnace steel making process is classified as a hazardous wastes by Korean Environmental Protection Acts, mainly because of the existence of water soluble heavy metals (Pb, Zn and Cd). Thus the treatment of EAF dust is being carried out to fulfill both the environmental aspect and recovery of valuable metals. To establish the proper process for recovering the valuable metals (Fe, Zn, Pb and Cd) and producing the non-toxic slag from EAF dust, many processes have been proposed. The feasibility study using RAPID-10 system have been carried out to find out the scale-up factor for designing the commercial scale EAF dust treatment process (capacity: 50,000 ton EAF dust per year) entilted RAPID-50 system. The design and construction of RAPID-50 (RIST Arc Plasma Industrial Device) system for treating 50,000 ton of EAF dust per year is now undergoing. Overall plan for treating EAF dust generated in KOREA will be setup after successful operation (December, 2002) of RAPID-50 system.
