• In order to develop a zinc recovery process from zinc-bearing dusts generated from ironmaking and steelmaking plants, fundamental and commercial scale experiments were carried out. Zinc-bearing dusts were mixed with cement and fine coke, and agglomerated as pellets or briquettes. These agglomerates were sharged into hot metal discharged from a commercial blast furnace. These tests indicated that zinc in the agglomerates was mostly vaporized, and the vaporized zinc was condensed in the collected dusts as zinc oxide. During the operation, a drop in the temperature of the hot metal was evaluated to be less than 10°C compared to the case by no charging.
