Electric arc furnaces (EAF) generate much dust during operation, which contains very high percentages of zinc, lead, and iron, as well as toxic organic substances. It is difficult to landfill it for environmental reasons, and not desirable in terms of wasting metal. However, most of the EAF dust is not processed sufficiently to make it harmless and to recover valuable metals.

Rotary kiln process is the main stream of present EAF dust treatment, but they still have the weakness of iron-including clinker disposal. Smelting reduction process has the advantages of almost complete metal recovery and detoxification of the dust, but it was not economically competitive because of higher energy cost. But the situation is changing with the increase of metal prices and severe environmental regulation.

EAF dust composition. The main components are 30 % zinc, 20 % iron, and 5 % chlorine, and dioxins in EAF dust are reported to be 0.5-5.0 ng-TEQ/g-dust. Most of the metals in the dust exist as oxides or chlorides.
