Abstract
Methods and apparatus for processing electric arc furnace ('EAF') dust through a basic oxygen furnace (BOF) to recover iron value from the EAF dust and concentrate zinc from the EAF dust into a material useful as a feed in zinc manufacturing processes. The method results in the reduction of the burden for the regulatory tracking of EAF dust. In addition, the method provides economic savings which result from the reduction of processing fees and the recovery of the value of iron and zinc materials. The apparatus involves the use of existing equipment that is used to recover iron value from other materials generated at steel making facilities, or the installation of new equipment for the purpose of iron reuse.
