A Look at the Process of Recycling EAF Dust - FEECO

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 with water.

What We Do - American Zinc Recycling

Today, EAF dust is recycled and recovers valuable metals. EAF dust contains valuable non-ferrous metals, especially zinc, nickel, and iron. It also contains smaller amounts of lead, chromium, and cadmium which can be harmful to human health and the environment. At our five recycling facilities, EAF dust is recycled and valuable metals are reclaimed for downstream use in a variety of markets.
