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.
