EAF dust is a by-product of the steel production process, and refers to the dust collected during the melting of steel in an electric arc furnace. Global estimates for EAF dust production currently sit between 5 to 10 million tons annually, a staggering amount, considering the steel industry continues to experience rising demand.
EAF dust has long imposed significant waste disposal costs on the steel industry, not only because of the volume at which it is produced, but also because the dust must either be chemically or thermally treated before it can be disposed of in a landfill – a costly endeavor.
As society continues to move toward more sustainable disposal methods, an alternative technique for handling EAF dust has been gaining interest: recycling EAF dust via reduction roasting.
Zhengzhou Hengyang Industry deploys the reliable rotary Kiln technology that successfully processes over 80% of the world’s recycled steel dust (EAF Dust). The rotary Kiln process is an established, energy-efficient and resilient technology used to treat zinc containing materials and residues.

Rotary Kiln Zinc Oxide is the main product of recycling EAF dust utilizing the Waelz Kiln technology. This product is sold to zinc smelters as an alternative to traditional zinc concentrates from mines. The zinc smelters produce pure zinc ingots or other high purity zinc products that are either sold to the steel industry for galvanization purposes or sold to other end-users for pigments, tires, chemicals or medicines.
