Abstract

Recycling of valuable metals such as Zn, Pb is a key issue for environmental protection and efficient utilizations of valuable metals. In order to recover Zn and Pb from iron and steelmaking dusts, the recovery process of these dusts by microwave heating was investigated. Zn and Pb were almost 100% recovered from these dusts by microwave heating. In the first stage of this process, reduction of Fe2O3 proceeded prior to that of ZnO. In the second stage, when the temperature of the sample was above 900°C, ZnO was reduced and Zn was vaporized.
