Recovering zinc and other metals from EAF dust via reduction roasting is a fairly simple process. A typical EAF dust recycling process looks like this: The kiln feed material, comprised of zinc 'waste,' fluxes, and reductant (coke), is typically pelletized before addition to the kiln. First, however, EAF dust is pre-conditioned via blending ...
